  • Patent number: 6090900
    Abstract: Homopolymers of olefin monomers having polar functional groups, and copolymers of these monomers with each other and with non-polar olefins and optionally carbon monoxide are disclosed. The polymers can be prepared by contacting the corresponding monomers with a transition metal catalyst under comparatively mild conditions; this preserves at least some of the polar functional groups in the resulting polymer.
