  • Process for polymerization of cycloolefins and polymerizable cycloolefins
    Patent number: 6677418
    Abstract: Process for the catalytic copolymerisation (ROMP) of strained activated cyclic olefins comprising contacting an activated strained mono (poly)cyclic olefin monomer of formula with at least 1 wt % of an activated strained di (poly)cyclic olefin monomer of formula in the presence of a catalyst or an initiating agent wherein the group represents a strained (poly)cyclic olefin, tail Y and spacer X comprise preferably electron withdrawing and property modulating groups whereby the monomers form a copolymer comprising the repeating unit and at least 1 wt % of the unit which 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 produc
