Polar monomer-olefin-copolymer, useful as acrylic rubber, comprises a polar monomer unit, an olefin unit and a chain structure containing two or more olefin units

摘要

Polar monomer-olefin-copolymer (A) comprises a polar monomer unit (I) (50-75 mol.%) and an olefin unit (II) (25-50 mol.%) (where the total quantity of both units constitutes 100 mol.%); and a chain structure (III) containing two or more olefin units. Independent claims are included for the preparations of (A).
