Abstract
A polymeric material having high impact resistance and improved resistance to ageing is prepared by grafting monomers such as acrylonitrile and styrene upon a rubbery terpolymer of ethylene, an alpha-olefin such as propylene and a triene termonomer such as 2-(1' or 2' or 3' methyl-1' or 2' or 3' cyclopenta-2' or 4' dienyl) norborn-5-enyl-methane, containing from 0.1 to 20 pairs of conjugate double bonds per thousand carbon atoms in the polymer chain.
