    • A polymer latex composition comprising a polymer with a glass transition temperature (Tg) of -85 to +30°C and a polymer with Tg of +40 to +140°C, wherein the polymers are dispersion-stabilized with polyvinyl alcohol (PVA). Preferably, the polymer latex composition is (1) a coating composition comprising a first polymer with Tg of -20 to +30°C and a second polymer with Tg of +60 to +140°C, or (2) used for preparation of a dip-forming coagulating composition comprising a coagulant and a polymer latex comprising copolymer particles each having PVA bonded thereto, which are obtainable by polymerizing a monomer capable of forming a third polymer with Tg of -85 to +10°C in a first step, and then a monomer capable of forming a fourth polymer with Tg of +40 to +140°C in the sequential step. The polymerization for preparing the first through fourth polymers is carried out in the presence of PVA in an aqueous medium.
    • 一种聚合物胶乳组合物,其包含玻璃化转变温度(Tg)为-85至+30℃的聚合物和Tg为+ 40至+ 140℃的聚合物,其中聚合物用聚乙烯醇(PVA)分散稳定, 。 优选地,聚合物胶乳组合物是(1)包含Tg为-20至+30℃的第一聚合物和Tg为+60至+ 140℃的第二聚合物的涂料组合物,或(2)用于制备 浸渍形成凝固组合物,其包含凝结剂和包含各自具有PVA键合的共聚物颗粒的聚合物胶乳,其可通过在第一步骤中使能够形成Tg为-85至+10℃的第三聚合物的单体聚合而获得, 然后在顺序步骤中能够形成Tg为+ 40至+ 140℃的第四聚合物的单体。 用于制备第一至第四聚合物的聚合在PVA的存在下在水性介质中进行。
