You should use the biodegradable polymers in day to day life. The routine use of very thin plastic bags has created very real hazard in your life. The This plastic does not decompose and has been creating a serious hazard, specially in developing countries. Stray cows eat the plastic bags, which they can not digest. These plastic waste is washed to sea and sea animals have been dieing due to consumption of plastic material. You can not burn the plastic bags. They create the toxic fumes. So plastic has to be recycled. It is better to use the biodegradable material, which will be ecofriendly in long term.
Perma flow thickener is typically composed of a blend of biopolymers and other ingredients designed to increase the viscosity or thickness of a fluid. The specific composition can vary depending on the manufacturer and intended application but commonly includes guar gum, xanthan gum, and other additives to improve performance.
Some disadvantages of chitosan-based biopolymers include limited mechanical strength, potential allergenicity for individuals with shellfish allergies, and variability in properties depending on the source and processing methods used to produce the chitosan. Additionally, chitosan can be expensive compared to traditional petroleum-based polymers.
It depends on what your definition of a chemical is. It is a molecule, and you can react it with other chemicals to form different products, so I would say it is a chemical. You can also synthesize proteins in labs, so that also would point to it being a chemical.
A molecule containing a very large number of atoms.
Organic Chemistry: deals with compounds containing carbon (which is pretty much everything living)Inorganic Chemistry: deals with noncarbon compounds and non-living matter.Physical: deals with the relations between the physical properties of substances and their chemical formations along with their changes.Biochemistry: deals with the composition and changes in the formation of living species.Analytical: deals mostly with the composition of substances.Pharmaceutical: chemistry behind pharmaceutical preparations.Theoretical: usually closely related to physical; has to do with the prediction of chemical properties based on theoretical principals.Polymer: study of, well, polymers (often synthetic, but sometimes biopolymers also).There's considerable overlap between many of these: it's certainly possible to be a physical organic chemist, or a theoretical biochemist, or an analytical polymer chemist, to name just a few combinations based on people I actually know.It's also possible to specialize even further and work exclusively with, say, compounds containing a particular element (other than carbon) such as boron or a group of closely related elements like the lanthanides, or to specialize in a particular subdivision of analytical and/or physical chemistry such as spectroscopy. This makes an exhaustive list essentially impossible, because someone will always manage to find a new niche.
Biopolymers are derived from renewable resources, making them more sustainable and environmentally friendly compared to traditional plastics. Additionally, biopolymers have the potential to biodegrade more easily, reducing pollution and waste in the environment.

There is huge scope for polymers because of thir application in various fields. eg. biopolymers, manf of appliances, catalyst supports, hydrophilic polymers, in medicines, in surfactants etc.
