Polyketone preparation from regulated quotient mixture of olefins

摘要

The invention is a linear random terpolymer comprised of repeating units of -CO-(C2H4)- and units of -CO-(CxHy)- where x is greater than 2 and less than 20, having a melting point between about 150 DEG C. and about 245 DEG C. The invention also concerns a process to prepare a polymer having a melting point less than about 245 DEG C. which comprises contacting carbon monoxide and ethylene in the presence of one or more hydrocarbons CxHy containing an olefinically unsaturated -CH=CH- group, where x is greater than 2 and less than 20, with a suitable catalyst and under conditions effective to prepare a linear random polymer having units of the formula -CO-(C2H4)- and units of the general formula -CO-(CxHy)-, and having a melting point less than about 245 DEG C.
