polyolefins
section::::polyolefins.









































many common addition polymers are formed from unsaturated monomers (usually having a c=c double bond). the most prevalent addition polymers are polyolefins, i.e. polymers derived by the conversion of olefins (alkenes) to long-chain alkanes. the stoichiometry is simple:









































this conversion can be induced by a variety of catalysts including free radicals, acids, carbanions and metal complexes.









































examples of such polyolefins are polyethenes, polypropylene, pvc, teflon, buna rubbers, polyacrylates, polystyrene, and pctfe.

addition polymer
alkenes react in many addition reactions, which occur by opening up the double-bond. most of these addition reactions follow the mechanism of electrophilic addition. examples are hydrohalogenation, halogenation, halohydrin formation, oxymercuration, hydroboration, dichlorocarbene addition, simmons–smith reaction, catalytic hydrogenation, epoxidation, radical polymerization and hydroxylation.
