본 발명은 LCST 화합물에 의해 수성 매질 중의 엘라스토머 에틸렌/α-올레핀 공중합체 입자의 응결을 감소시키거나 방지하는 방법에 관한 것이다. The teachings herein relates to elastomeric particles including 98.5 weight percent or more of an elastomeric ethylene/α-olefin copolymer. The copolymer preferably has a weight average molecular weight of 10 to 2,000 kg/mol. The copolymer preferably has a Mooney viscosity of at least 10 (ML 1+4 at 125° C., ASTM D1646). The particles preferably include 0 to 0.4 weight percent of salts of multivalent metal ions. The salts of multivalent metal ions preferably includes stearates and palmitates of multivalent metal ions. The elastomeric ethylene/α-olefin copolymer preferably is an EPM or an EPDM. The blends including the particles preferably comprise a different elastomer, a filler, or a curing system.
