Process for the catalytic copolymerisation (ROMP) of strained activated cyclic olefins comprising contacting an activated strained mono (poly)cyclic olefin monomer of formulawith at least 1 wt % of an activated strained di (poly)cyclic olefin monomer of formulain the presence of a catalyst or an initiating agent wherein the grouprepresents a strained (poly)cyclic olefin, tail Y and spacer X comprise preferably electron withdrawing and property modulating groupswhereby the monomers form a copolymer comprising the repeating unitand at least 1 wt % of the unitwhich is adapted for subsequent cross linking of respective copolymer chains in the presence of heat and catalyst to form an amount of a cross linked copolymer comprising the unit,and polymeric products obtained thereby, novel monomers and intermediates, a method for selecting monomers for reaction a method for the preparation of shaped products by RIM or RTM, and shaped products obtained thereby.
