본 발명은 중합체-O-Si-O-중합체 연결을 가진 에폭시-관능성 및/또는 아미노-관능성 중합체 및 카르복실산 기 및/또는 카르복실산 무수물 기를 가진 폴리올레핀 (공)중합체의 용융-블렌딩된 네트워크를 포함하는 유기 용매-기반 분산액의 제조 방법에 관한 것이며, 본 방법은 a) 용매의 부재 하에, 예비중합체, 실란-관능성 화합물 및 폴리올레핀 (공)중합체로부터 용융-블렌딩된 네트워크를 형성하는 단계, b) 상기 용융-블렌딩된 네트워크를 유기 용매와 혼합하여, 유기 용매-기반 분산액을 형성하는 단계, 및 c) 상기 유기 용매-기반 분산액을 냉각시키는 단계 를 포함한다. 본 발명은 추가로, 코팅 조성물, 및 코팅된 금속 기판에 관한 것이다. The invention relates to a process for preparing an organic solvent-based dispersion comprising a melt-blended network of an epoxy-functional and/or amino-functional polymer having a polymer-O-Si-O-polymer linkage and a polyolefin (co)polymer having carboxylic acid and/or carboxylic acid anhydride groups, the process comprising the steps of a) forming the melt-blended network from a prepolymer, a silane-functional compound and the polyolefin (co)polymer in the absence of a solvent, b) mixing the melt-blended network with an organic solvent to make the organic solvent-based dispersion, and c) cooling the organic solvent-based dispersion. The invention further relates to a coating composition and to a coated metal substrate.
