Peroxy-terminated poly(epsilon-caprolactones) of formula (A-X)m-R-(X'-B)n (I), are new. A = H-(O-(CH2)5-C(O))y-; B = (i); m = 0-3; n = 1-4; (m+n) = 1-4; R1,R2 = 1-4C alkyl; R3 = 1-12C alkyl or 2-12C acetylenic; y = 0-10000; x = 4-22000; (y)(m)+(x)(n) = 4-22000; X,X' = -O- or -N(R4)-; R = opt. substd. aliphatic, alicyclic, aromatic or araliphatic (di-, tri- or tetra-) radical; when n+m = 1, R = opt. substd. radical selected from 1-20C aliphatic, 5-18C alicyclic, 6-14C aromatic, 7-22C araliphatic and (non)aromatic 5-12C heterocyclic; when n+m = 2, R = opt. substd. diradical selected from 2-20C aliphatic, 4-20C aliphatic interrupted by 1-3 -O-, -S- or -N(R4)- gps. in the chain provided that multiple heteroatoms are sepd. from each other and the diradical chain ends by at least 2C, 5-18C alicyclic, 6-12C aromatic where R is a hydrocarbon with 2 free valencies and an aromatic carbocyclic unit(s), and 7-22C araliphatic; when n+m = 3, R = opt. substd. triradical selected from 3-20C aliphatic, 5-18C alicyclic, 6-14C aromatic and 7-22C araliphatic; when n+m = 4, R = opt. substd. tetraradical selected from 4-20C aliphatic, 6-18C alicyclic, 6-14C aromatic and 7-22C araliphatic; R4 = H or opt. substd. 1-20C aliphatic, 5-18C alicyclic, 6-14C aromatic or 7-22C araliphatic; and substits. for R and R4 = Cl, Br, 1-8C alkyl, 1-12C alkoxy, 6-10C aryloxy and/or cyano, and additional substits. for R = 1-4C acyloxy and/or (meth)acryloyloxy. |
