polyethylenicadj.

Brit.

/ˌpɒlɪɛθᵻˈlɛnɪk/,

/ˌpɒlɪɛθɪˈliːnɪk/, U.S.

/ˈˌpɑliˌɛθəˈlɛnɪk/

Origin: Formed within English, by compounding; originally modelled on a French lexical item. Etymons: poly- comb. form, ethylenic adj. at ethylene n. Derivatives

Etymology: < poly- comb. form + ethylenic adj. at ethylene n. Derivatives, originally (in sense 1) after French polyéthylénique (in alcools polyéthyléniques (plural): A. Wurtz 1860, in Compt. rend. Acad. Sci. 50 1195). Compare polyethylene n.

Chemistry.

1. Originally: designating polymeric compounds prepared from derivatives of ethylene (cf. polyethylene n. 1). Now: of, relating to, or of the nature of polyethylene.
