ABSTRACT Organic (co)polymers are modified by contacting them with an organic peroxide and decomposing the peroxide. To decompose also saturated (co)- polymers use is made of an organic peroxide having the general formula: R-(O-O-CH1-CR2=CR3R4)N, wherein N is 1, 2 or 3; R1 is H, C1-C4 alkyl or C2-C4 alkylene; R2, R3 and R4 are, independently, H or C1-C4 alkyl; two of the substituents R1-R4 together may form C3-C12 alkylene; and, when N is 1, R is an optionally hydroxyl substituted C4-C18 T. alkyl, P-menth-8-YL, C5-C18 T.alkenyl, 1-vinylcyclohexyl or a group of the formula: -C(CH3)2- C6HJ(5-M)-R5(M), wherein M is O, 1 or 2 and R5 is isopropenyl or 2-hydro- xyisopropyl; when N is 2, R is a C8-C12 alkylene or alkynylene group having a tertiary structure at both ends, or a group having the formula: -(C)CH3)2)2-C6H(4-X)-R5(X), wherein X is 0 or 1; and when N is 3, R is 1,2,4-or 1,3,5-triisopropylbenzene-alpha, alpha " -triyl, i.a., 3-allyl- peroxy-3,3-dimethylpropene according to a preferred embodiment the modi- fication is carried out in the presence of a coagent, whereby the advan- tageous polymer properties, sush as adhesion to polar materials, are further enhanced.
