Homopolymers of benzocyclobutenes of the formula <CHEM> R1 being H or CH3 and R2 being @CH2@@, where n is 0 to 6, and copolymers of such benzocyclobutenes with (a) C2-C8- alpha -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-Butenyl)benzocyclobutene is a novel compound.
