    摘要： Latex binders are disclosed which are used to prepare freeze-thaw-stable latex coating compositions which may be free of volatile freeze-thaw/open-time additives. The latex binders are prepared by combining a polymer which is the polymerization product of a polymerizable saccharide monomer, an acrylic monomer and, optionally, a monomer selected from styrenic monomers, ionic monomer and wet adhesion monomers. The latex coating compositions are freeze-thaw stable, even in the total absence of a volatile freeze-thaw additive, and exhibit improved open-time when compared to a latex coating composition which does not contain a volatile freeze-thaw additive. Methods for preparing the freeze-thaw-stable latex coating compositions are also disclosed.

    摘要翻译： 公开了乳胶粘合剂，其用于制备可以不含挥发性冻融/开放时间添加剂的冻融稳定的胶乳涂料组合物。 胶乳粘合剂是通过将作为可聚合糖单体，丙烯酸单体和任选的选自苯乙烯单体，离子单体和湿粘合单体的单体的聚合产物的聚合物组合而制备的。 即使在完全不存在挥发性冻融添加剂的情况下，胶乳涂料组合物是冻融稳定的，并且与不含挥发性冻融添加剂的胶乳涂料组合物相比，其表现出改善的开放时间。 还公开了制备冻融稳定乳胶涂料组合物的方法。
