纸张涂料组合物的粘合剂
摘要：
本发明提供用于纸张涂料组合物的聚合物分散体，其能够在一种或多种乳化剂和任选存在的保护胶体的存在下，通过以下组分的自由基引发的水性乳液聚合而得到：a)50‑93重量％的至少一种具有1‑12个C原子的链烷酸的乙烯基酯，其均聚物的玻璃化转变温度Tg低于约350°K，b)2‑30重量％的乙烯，c)5‑20重量％的至少一种单体，其均聚物的玻璃化转变温度Tg至少为约350°K，d)0.1‑2重量％的烯键式不饱和硅烷单体，e)0‑5重量％的能够与醋酸乙烯酯和乙烯共聚的其他烯键式不饱和单体，各种情况下都是基于用于聚合的单体的总重量，在各种情况下所述重量％数据之和都是100重量％。
摘要（英）：

The invention provides a polymer dispersion for paper coating compositions, obtainable by means of a radically initiated, aqueous emulsion polymerization in the presence of one or more emulsifiers and optionally protective colloids, of a) 50 to 93 % by weight of at least one vinyl ester of an alkanoic acid with 1 to 12 C-atoms, whose homopolymer has a glass transition temperature Tg of below about 350 DEG K, b) 2 to 30 % by weight of ethylene, c) 5 to 20 % by weight of at least one monomer whose homopolymer has a glass transition temperature Tg of at least about 350DEGK, d) 0.1 to 2 % by weight of ethylenically unsaturated silane monomers, e) 0 to 5 % by weight of further ethylenically unsaturated monomers that are copolymerizable with vinyl acetate and ethylene, based in each case on the total weight of the monomers used for the polymerization, with the data in % by weight summing in each case to 100% by weight.
