A polyolefin is a type of polymer with the general formula (CH2CHR)n where R is an alkyl group. They are usually derived from a small set of simple olefins (alkenes). Dominant in a commercial sense are polyethylene and polypropylene. More specialized polyolefins include polyisobutylene and polymethylpentene. They are all colorless or white oils or solids. Many copolymers are known, such as polybutene, which derives from a mixture of different butene isomers. The name of each … WebAlkyd resins can be regarded as a class of modified condensation polymers. 73 Originally, alkyd resins were merely the reaction products of phthalic anhydride and glycerin, and were too brittle to make satisfactory coatings. However, the use of fatty oils or unsaturated fatty acids in combination with the brittle alkyds resulted in flexible, glossy, air-drying coatings, …
