Title:
ETHYLENE-(METH)ACRYLATE ELASTOMER AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/196794
Kind Code:
A1
Abstract:
An ethylene-(meth)acrylate elastomer having a structure that has been copolymerized at the proportions 40-79.9 mol% of ethylene, 20.0-50.0 mol% of an alkyl(meth)acrylate with a C1-8 alkyl group and/or an alkoxy(meth)acrylate with a C2-8 alkoxyalkyl group, 0.05-20.0 mol% of an unsaturated dicarboxylic acid, and 0.001-20.0 mol% of an unsaturated dicarboxylic acid anhydride, wherein the melt flow rate as measured under a load of 2.16 kg and at a temperature of 190°C is 0.01-100 g/10 minutes. This ethylene-(meth)acrylate elastomer provides a vulcanized product with superior heat resistance, oil resistance, and moldability.
