PURPOSE: Composite pressure sensitive adhesive micro spheres comprising two or more water insoluble polymers are provided which can be prepared by free radical suspension polymerization. CONSTITUTION: Composite pressure sensitive adhesive micro spheres are described comprising two or more water insoluble polymers that are mixed wholly within the boundaries of polymeric micro spheres. The range of monomers and polymers are chosen to tailor the properties of the composite pressure sensitive adhesive micro spheres for specific performance and/or application requirements. Any polymer that can be dissolved into a solvent monomer or mixture of solvent monomers can be used to prepare the composite pressure sensitive adhesive micro spheres. Pressure sensitive adhesive micro spheres according to this process can be prepared using free radical suspension polymerization. 본 발명은 중합체 미소구의 경계 내에 존재하여 완전히 혼합되어 있는 물에 불용성인 2종 이상의 중합체를 포함하는 복합 감압성 접착제 미소구를 제공한다. 일련의 단량체 및 중합체는 특정 성능 및/또는 용도의 필요 조건에 적합한 복합 감압성 접착제 미소구의 성질을 조정할 수 있도록 선택해야 한다. 용매 단량체 또는 용매 단량체의 혼합물 내로 용해될 수 있는 모든 중합체는 복합 감압성 접착제 미소구를 제조하는데 사용할 수 있다. 본 발명에 따른 감압성 접착제 미소구는 자유 라디칼 현탁 중합을 사용하여 제조할 수 있다.
