実験手順

In this example the starting monomers allene and phenylacetylene (HC≡C--O) are introduced into the catalyst mixture of Example 1 in a feed ratio of 62 to 38 (mole ratio). The polymerization conditions and catalyst are the same as in Example 1. After stirring at 60° C. for ten hours, a copolymer with a molecular weight of about 25,000 daltons (measured by GPC) is produced and can be isolated by precipitation to methanol. Given a starting amount of 0.5 g allene and 1.18 g phenylacetylene, the yield of copolymer will be 1.5 g, and have the formula: ##STR13##
