Step-by-step solution
Thermoset plastics retain their form and stay solid under heat once cured. Urea-formaldehyde is an example of thermosetting polymer. Polymers which disintegrate by themselves over a period of time due to environmental degradation by bacteria etc. are called biodegradable polymers. Nylon-2-nylon-6 is an example of biodegradable polymer. Any artificial elastomer is referred to as synthetic rubber. Buna-N is an example of synthetic rubber. Polyester is a synthetic or man-made fiber material. Dacron is an example polye
