ABSTRACT:
The invention features linear copolymers prepared from mixtures of allenes and alkynes. The new copolymers have the formula: ##STR1## wherein R.sub.1 through R.sub.6 are, independently, H, an alkyl, an aryl, a phenyl or substituted phenyl, an alkoxy, or an aryloxyl, x+n is 1 to 10,000, and m is 1 to 10,000. The invention also features efficient methods of preparing the new copolymers using nickel or palladium catalysts.
