A process for producing a molded article by introducing a reactive liquid mixture which comprises a cycloalkene containing dicylopentadiene, a norbornene-type monomer containing at least one N-substituted 5-membered cyclic amide group and a metathesis polymerization catalyst system and which has moderated metathesis polymerizability into a mold in which the liquid mixture is metathesis polymerized, and a multi-part polymerizable composition for producing the molded article.
A cross-linked copolymer containing repeating units derived from dicyclopentadiene and metathesis polymerizable halogen-containing cycloalkenes, a process for producing the copolymer, a process for producing a molded article from the copolymer and a polymerizable composition therefor.
A cross-linked copolymer comprizing repeating units derived from a mixture comprising metathesis polymerizable cyclic compounds such as dicyclopentadiene and carboxylic acid esters of which the acid residue and alcohol residue have individually at least one norbornene-moiety, a process for producing the copolymer, a process for producing a molded article from the copolymer and a polymerizable composition therefor.
A cross-linked copolymer containing repeating units derived from a mixture comprising the following monomers:
or
and occasionally other repeating units derived from other metathesis polymerizable cyclic compounds such as dicyclopentadiene, a process for producing the copolymer, a process for producing a molded article from the copolymer and a polymerizable composition therefor.
