    • A process for producing an aqueous emulsion of a silicone graft copolymer by forming an emulsion of particles having a diameter of 0.5 (my)m or less from a silicone (macromonomer) having a radical-polymerizable functional group and another vinyl monomer by dispersing the monomers in water in the presence of a surfactant having a radical-polymerizable functional group and copolymerizing the monomers by heating, wherein the macromonomer contains 5-80 wt. % of a macromonomer having less than 20 repeating silicone structure units. The process can provide an aqueous emulsion excellent in stability, water repellency and mold release characteristics, because the features of the silicone component can be fully exhibited while retaining a high reactivity. The obtained emulsion can be widely used in the fields of coating resin, paper converting agent, textile finishing agent, film converting agent, civil engineering resin, adhesive, pressure-sensitive adhesive, mortar binder, concrete binder, and so forth.
    • 通过将具有自由基聚合性官能团的硅氧烷(大分子单体)和其它乙烯基单体通过分散单体形成直径为0.5(my)m以下的颗粒的乳液,制造有机硅接枝共聚物的水性乳液的方法 在具有自由基聚合性官能团的表面活性剂存在下,通过加热使单体共聚,其中大分子单体含有5-80wt。 %的具有少于20个重复硅氧烷结构单元的大分子单体。 该方法可以提供稳定性,防水性和脱模特性优异的水性乳液,因为可以充分展示硅氧烷组分的特征,同时保持高反应性。 所得乳液可广泛用于涂料树脂,纸张转化剂,纺织整理剂,薄膜转化剂,土木工程树脂,粘合剂,压敏粘合剂,砂浆粘合剂,混凝土粘合剂等领域。
