Abstract
A polyolefin composition comprises repeating units of a metathesis polymerizable olefin monomer, a metathesis polymerization procatalyst, a metathesis polymerization procatalyst activator, and at least one member selected from the group consisting of: (i) a Lewis acid catalyst and a Lewis acid cocatalyst, effective to obtain a residual metathesis polymerizable olefin monomer level of from 0 to 0.25 weight percent, based on the weight of the polyolefin; (ii) an anionic polymerization catalyst; (iii) a free radical polymerization initiator; and (iv) a hydrosilation polymerization catalyst. The method for making the composition is also disclosed. The use of metathesis polymerization in conjunction with another type of polymerization can achieve a variety of beneficial effects, including a very low level of residual metathesis polymerizable monomer.
