본 발명은 올레핀 블럭 공중합체, 분산제, 바람직하게는 에틸렌 아크릴산, 및 물을 포함하는 수성 폴리올레핀 분산액 조성물로부터 분무 스킨을 제조하는 방법에 관한 것이며, 여기서 상기 수성 분산액은 바람직하게는 12 pH 미만을 갖고 용융 블렌딩으로부터 유도된다. 상기 방법은 수성 폴리올레핀 분산액을 스킨을 형성하는 가열된 금형에 분무하는 단계 및 그 후 이를 건조시키는 단계를 포함한다. The present invention relates to method to make a spray skin from an aqueous polyolefin dispersion composition comprising a an olefin block copolymer, a dispersing agent, preferably an ethylene acrylic acid, and water, wherein said aqueous dispersion preferably has a pH less than 12 and is derived from the melt blending. The method comprises the steps of spraying the aqueous polyolefin dispersion onto a heated mold forming the skin and then allowing it to dry.
