any of a group of thermoplastic polymers, as polyethlylene or polypropylene, made from any simple alkene
Word origin
poly- + olefin
polyolefin in American English
(ˌpɑliˈouləfɪn)
noun
Chemistry
any of a group of thermoplastic, stiff, light, and hard polymers obtained from the polymerization of simple olefins like propylene, used for injection molding, mostly in the automotive and appliance industries
Word origin
[poly- + olefin]poly- is a combining form with the meanings “much, many” and, in chemistry, “polymeric,”used in the formation of compound words. Other words that use the affix poly- include: polyandrous, polyculture, polyethylene
