• Modification of vinyl dispersion resins for improved elasticity
  申请人：THE B.F. GOODRICH COMPANY

  公开号：EP0347769A1

  公开（公告）日：1989-12-27

  The elasticity and dynamic moduli of dispersion grade vinyl resins (particularly polyvinyl chloride homopolymers and copolymers derived predominantly from vinyl chloride monomer) are significantly improved by simply blending into a latex of such a vinyl resin a minor proportion of an acrylic rubber latex, the rubbery polymeric solids in which have a glass transition temperature below 0°C. More specifically, said rubber polymeric solids are produced by emulsion polymerization of the following monomers: (a) about 80 to about 98 parts by weight of alkyl acrylates averaging at least 2 carbon atoms per alkyl group; (b) about 1 to about 10 parts by weight of unsaturated dicarboxylic acids containing between 4 and about 8 carbon atoms; and (c) optionally up to 19 weight parts of compatible, additional unsaturated monomers. The resultant, blended latex can be used per se, but is preferably spray dried to form a modified, fine, plastisol grade vinyl resin powder the primary particles of which are mostly from less than 1 to about 2 microns in size. Fluid plastisols formulated from said spray dried resin offer special advantages for use in forming articles requiring greater elasticity and aesthetic tone("feel") than can be obtained from conventional polyvinyl chloride plastisols.

  只需在乙烯基树脂胶乳中掺入少量丙烯酸橡胶胶乳，分散级乙烯基树脂（特别是主要由氯乙烯单体衍生的聚氯乙烯均聚物和共聚物）的弹性和动态模量就能得到显著改善，其中的橡胶聚合固体的玻璃化转变温度低于 0°C。更具体地说，上述橡胶聚合固体是通过以下单体的乳液聚合生产出来的： (a) 约 80 至约 98 重量份的丙烯酸烷基酯，每个烷基平均至少有 2 个碳原子； (b) 以重量计，约 1 至约 10 份含有 4 至约 8 个碳原子的不饱和二羧酸；以及 (c) 可选的最多 19 重量份的相容的额外不饱和单体。 混合后的胶乳本身可以使用，但最好经过喷雾干燥，以形成改性的、精细的塑溶胶级乙烯基树脂粉末，其主要颗粒的尺寸大多小于 1 微米到大约 2 微米。与传统的聚氯乙烯塑料溶胶相比，用上述喷雾干燥树脂配制的流体塑料溶胶具有特殊的优势，可用于制作要求更高弹性和美观色调（"手感"）的物品。
