Abstract
A polymer prepared by metathesis polymerizing at least one compound represented by the formula ##STR1## wherein m is 0 or 1 and R.sub.1 and R.sub.2 respectively represent hydrogen atom or an alkyl group containing up to three carbon atoms provided that both R.sub.1 and R.sub.2 are not hydrogen atom at the same time, or a mixture of said compound with at least one other metathesis polymerizable comonomer, a useful molded article, processes for preparing the polymer and a polymerizable composition therefor.
Claims87
A polymer which comprises at least one repeating unit having the formula selected from the group consisting of ##STR14## wherein R.sub.1 and R.sub.2 independently represent a hydrogen atom or an alkyl group containing up to three carbon atoms provided that both R.sub.1 and R.sub.2 are not hydrogen atoms.
A multi-part polymerizable composition comprising at least one compound of the formula (III) ##STR17## wherein m is 0 or 1 and R.sub.1 and R.sub.2 independently represent a hydrogen atom or an alkyl group containing up to three carbon atoms, provided that both R.sub.1 and R.sub.2 are not hydrogen atoms or a mixture of said compound with at least one other metathesis polymerizable comonomer;
- and a metathesis polymerization catalyst system comprising a catalyst and an activator, said catalyst and said activator being not present in the same part.
A composition of claim 76 wherein m is 1.
