WebOct 23, 2024 · Don't be misled by chemical formulas that depict polymers such as polyethylene as reasonably straight chains of substituted carbon atoms. Free rotation around C—C bonds allows long polymer molecules to curl up and and tangle very much like spaghetti. Thus polymers generally form amorphous solids. WebApr 9, 2024 · It is known as cis- 1, 4- polyisoprene and is produced by polymerizing isoprene (2 methyl-1, 3-butadiene) with the chemical formula (C5H8)n. They are rendered by loosely linking the monomers of isoprene (C5H8) in the form of a long tangled chain, in simple terms. Given below is rubber polymer structure and natural rubber formula.
