Polymeric compositions which may be readily crosslinked at temperatures above about 200 °C comprise an elastomeric polymer possessing olefinic unsaturation and an effective amount of a benzocyclobutene derivative of the general formula
where "X" is selected from the group consisting of -CH=CH-
and -(R)-where "R" is an alkylene group of 1 to 10 carbon atoms. Cured compositions are also claimed.

Homopolymers of benzocyclobutenes of the formula
R, being H or CH3 and R2 being (̵CH1 )̵n, where n is 0 to 6, and copolymers of such benzocyclobutenes with (a) C2-C8-α-monoolefins, (b) monoalkenylarenes which are random copolymers and (c) monoalkenylarenes which are block copolymers, n being zero and the conjugated diene polymer block optionally being hydrogenated, and processes for the preparation of such polymers by (co)polymerization of the appropriate monomers in the presence of a catalyst. 4-(3-Butenyi)benzocyclobutene is a novel compound.
