A monomer comprises a reactive arylcyclobutene moiety and a molecular group which is bonded to the aryl group of the arylcyclobutene moiety. The molecular group can comprise an organic molecular group, especially at least one unsaturated alkyl group, ie. a group of two aliphatic or alicyclic carbon atoms bonded by a double or a triple bond, or an inorganic molecular group. Suitable organic molecular groups include aliphatic, cyloaliphatic, heterocyclic and aromatic moieities. Polymers are prepared by reacting the monomeric compounds of the invention under polymerization conditions, optionally in the presence of copolymerizable monomers.
