Organic (co)polymers, including saturated (co)polymers, are modified by contacting them with an organic peroxide and decomposing the peroxide. Use is made of an organic peroxide having the general formula R-(O-O-CHR1-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 0, 1 or 2 and R5 is isopropenyl or 2-hydroxyisopropyl; 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-allylperoxy-3,3-dimethylpropene according to a preferred embodiment the modification is carried out in the presence of a coagent, whereby the advantageous polymer properties, such as adhesion to polar materials, are further enhanced.
