  • Ethylene copolymerisates having improved low-temperature properties and good oil resistance, vulcanizable mixtures made therefrom and vulcanizates
    Patent number: 10370472
    Abstract: The present invention relates to copolymers of ethylene, vinyl esters of an alkyl carboxylic acid and other specific unsaturated carboxylic esters which have lower glass transition temperature than copolymers of ethylene and vinyl esters of an alkyl carboxylic acid, and also to production and use of these, to vulcanizable mixtures comprising the copolymers of the invention, to crosslinking of these and to vulcanizates and moldings obtainable therefrom.
