When a shape memory polymer is used to stitch a wound loosely, the temperature of the body makes the thread tighten and close the wound, applying just the right amount of force. This is an example of a 'smart' polymer. i.e. one that changes in response to changes around it. In this case a change in temperature causes the polymer to change its shape. Later, after the wound is healed, the material is designed to dissolve and is harmlessly absorbed by the body. Hope this helps:)
They have more useful properies than other polymers
It didn't work. Science is all about figuring out how things work. Alchemy doesn't work, and never did.
Hairspray is made up of a bunch of different chemicals. These chemicals work together to make a glue like substance.
You heat it until it becomes soft, but not so hot that it catches fire. Some polymers decompose before melting, so it may not always work.
Glues like the ones used at school are made up of long chains called polymers, which are a bit like spaghetti strands. When you glue 2 pieces of paper together the polymers get into all the microscopic cracks and crevices in the paper, (a bit like ink soaking into the porous surface of paper). As it dries and the water evaporates the polymer molecules are left in the cracks to hold the paper together. But not all glues work like this. Sometimes the glue contains a substance that temporarily melts the 2 surfaces you're trying to stick together, effectively welding them together when theglue dries. Superglue contains cyanoacrylate. When this substance comes into contact with water it forms chains which bond to the ends of the 2 things you're trying to stick together. As the glue dries the chains harden until they can't move.
They are used in hospitals as stitches because they will desolve in light and there is no need for them to be taken out.

PET, plasters that are exposed to light and reduces stickyness so removing plasters is less painful, dissovable stitches, drug delivary capsuels...

Turning chain. These are the stitches you make before you turn your work to begin another row. The number varies with each stitch. These stitches bring your work to the correct height before you make additional stitches. For single crochet that tch does not count as a stitch. For double crochet and all taller stitches, it does count as a stitch.
It is possible to use a smart card with the Nintendo DS to play pirated games. This has been made illegal.
In crochet, a fan stitch is a group of stitches worked into one stitch. In most cases the stitches would be a combination of chains and stitches. For example, you might work double crochets separated by chain stitches or you might work 4 double crochets, a chain, and then another 4 double crochets. It doesn't have to be 4. It can be any number. The stitches should look similar to a paper fan or scallop. If the pattern calls for multiple rows of fan stitches, they are generally placed one on top of the other. Fan stitches can be small or large and incorporate any number of stitches, but the individual stitches are all worked into one stitch from the previous row.

No. It can rip the stitches. Lay down and put a pillow under your knee and another under your foot and watch TV.
