Abstract

Linear, thermoplastic, elastomeric copolymers comprise carbon monoxide and at least one olefinic C.sub.7 - to C.sub.20 -monomer and have an average molecular weight M.sub.w greater than 15,000 g/mol and a T.sub.g -value of less than -20.degree. C., and comprise carbon monoxide, at least one olefinic C.sub.2 - to C.sub.4 -monomer and at least one olefinic C.sub.6 - to C.sub.20 -monomer and have an average molecular weight M.sub.w greater than 40,000 g/mol and a T.sub.g -value of less than 20.degree.
