What is acrylic polymer?
Acrylic polymers are compounds produced by bonding acrylic acid or acrylic ester with other molecules. Acrylic polymers utilize the desirable characteristics of acrylic acid and acrylic ester and are used in dispersants, thickeners, adhesives, binders, and paint vehicles.

You can use it as an adjective.
What additive keeps engines clean by keeping contaminates suspended in oil?
dispersants
What dispersants are used in oil spills?
It is spread in the water by an aircraft in the space where the oil spilled.
Why is it hard for scientists to keep track of dispersant?
because dispersants can be a gas and also once you put dispersants out there in the ocean other things are n there so it could get a little messed up or mixed together which makes it harder to keep track.
Are the chemicals being used by BP to clean up oil safe?
My answer is as of May 25, 2010. This is an ongoing event, and information can change rapidly. Yes, no and maybe! If a dispersant were sprayed in a body of water that did not have oil, it would be considered to be contaminating the water and ecosystem. They have special handling instructions to be applied safely. They are applied to break up another harmful substance, namely oil, and hasten the weathering/ evaporation process. The idea is that the remaining oil in a more dispersed (less concentrated) form will have less environmental impact. There is a natural degradation of oil by bacteria that occurs. The use of dispersants is controversial. Any use must be approved by the EPA. Decisions are done rapidly because in mitigating oil spills, time is of the essence. The particular dispersant that BP is using has toxic effects and there are ongoing discussions between EPA and BP on the current selections. Biologists have noted that if the dispersants are able to flow out of the gulf, there affect on corals could be devastating. An excellent summary of dispersants is attached. You can find many links on the particular dispersants being used by doing a google search. See related link.
How does oil dispersion work?
I think you are asking how do chemical dispersants work on oil. There are a number of chemical dispersants available. As indicated in the related link, a dispersant must contain a solvent, which is a substance that can dissolve into the oil. It must also contain a "surface active agent" or surfactant. You can visualize a surfactant as a having two sides, one that "likes water" or hydrophilic and the other that "likes oil or oleophilic. In this aspect, it is similar to dish washing soap that "cuts through the grease." However. the use of dispersants is controversial as chemical dispersant is not natural in the marine environment. It is a pollutant. To add a pollutant to an enormously polluting spill has caused controversy. However, the intent is to break up the spill, and reduce its impact as it comes closer to shore. Natural forces such as biological processes, evaporation and wave action further reduce or disperse the spill. Due to potentially toxic effects, no dispersant can be used on oil spills without government (EPA) approval. The government may put restrictions on what is used and how much is used. Dispersants have been used for several decades. There are notable limitations particularly in heavy oil spills where the chemical will just run off of the spill. BP is injecting dispersants on oil as it comes out of the well- a new application. See related link.
What are dispersants and do they work to clean up a spill?
Oil molecules naturally cling together. The binding forces are called the molecular cohesive forces. The dispersant mixes with water, helping to break apart the oil on the surface of the water. It does not really remove the oil from the water. It attempts to reduce the harmful effects of the spill and assist in the natural dispersion or mixing of oil and water. As shown in one of the links, there are toxic effects of dispersants on coral rocks which have marine biologists very concerned. See related link. Also, BP has a fact sheet under Joint Information Center webpage on the chemical composition of the dispersants.
How did the gulf oil spill affect the earth?
The Gulf of Mexico seabed seeps quite a bit of oil, anyway; the planet will surely have more difficulty recovering from the dispersants.
What is oil dispersent made of?
I have included one link describing oil dispersants in general and two fact sheets from Nalco- currenting being used in the oil spill in the gulf.
How do you find a way to clean oil from water without creating a bigger mess?
Removal of an oil spill from a water surface is not easy. In the current oil spill, oil is still coming out of the well (as of May 19) making the situation even more difficult. Oil slicks can be skimmed off and there are a number of skimmers available. The combination of skimmers, dispersants and containment booms are the most conventional means of cleaning up a small spill. Controlled burns have been used in the Gulf. This can eliminate large amounts of oil, but must be very regulated for safety and environmental reasons. Dispersants attempt to break up large oil spills, to promote dispersal and degradation by sea water. The use of dispersants in the current spill are being carefully regulated, because if not applied appropriately, they can create additional problems. Bacterial solutions are usually used for contaminated beaches or as done in Alaska, along the rocky coastline. See related link.
What factors made the Exxon Valdez oil spill difficult to control?
* Dispersants * Surface washing agents * Surface collecting agents * Bioremediation agents * Miscellaneous oil spill control agents

How can chemistry help to clean an oil spill and reduce its impact?
Dispersants help to degrade oil into naturally occurring substances quicker. Dispersants can be applied directly to spilled oil, and help to remove oil from the water surface where it is especially harmful. It does so by first breaking the surface oil slicks. As dispersants contain molecules with both a hydrophilic and lipophilic end, these molecules attach to oil, thus reducing interfacial tensions between the water and the oil, which helps break the oil slicks. After breaking the oil slicks, it disperses oil as fine droplets into the water column through natural mixing actions such as wave action and turbulence which dilutes the subsurface oil concentration. This disperses oil from water surface to water column. Afterwhich, oil is dispersed by currents and is subjected to natural processes such as biodegradation, which will render oil harmless.
