Abstract
An oligomer of the formula ##STR1## in which R.sub.1 =H or CH.sub.3 ; PA0 R.sub.2 =C.sub.t H.sub.2t in whcih 0.ltoreq.t.ltoreq.18; PA0 Z is selected from C.sub.2 H.sub.4, C2H2 and ##STR2## in which 2.ltoreq.d.ltoreq.16; m is an integer such that 1.ltoreq.m.ltoreq.3; PA0 R.sub.3 =C.sub.t'H.sub.2t'+1 in which t'.gtoreq.1 and 8.ltoreq.t+t'+2m.ltoreq.22 PA0 n and n' are identical or different integers, such that 2.ltoreq.n+n'.ltoreq.20; PA0 b is an integer equal to 0 or 1; and PA0 a is an integer ranging from 2 to 500. The invention also comprises the method of making the oligomer and thermoplastic films containing the same as well as the resultant thermoplastic films.
