  The density of rigid foamed articles made by the thermal decomposition of a blowing agent in a vinyl chloride polymer is reduced by the use of an organotin mercaptoalkylcarboxylate, alone, or in combination with an organotin halide or carboxylate which activate the blowing agent. Sulfides made from said organotin mercaptoalkylcarboxylate are also superior activators of the blowing agent.

  单独使用有机锡巯基烷基羧酸盐，或与有机锡卤化物或羧酸盐结合使用，可激活发泡剂，从而降低通过发泡剂在氯乙烯聚合物中的热分解制成的硬质发泡物品的密度。由上述有机锡巯基烷基羧酸酯制成的硫化物也是发泡剂的优质活化剂。
• A latent mercaptan as a heat stabilizer
  申请人：MORTON INTERNATIONAL, INC.

  公开号：EP0890608A2

  公开（公告）日：1999-01-13

  Both flexible and rigid vinyl chloride polymer compositions comprising a latent mercaptan-containing heat stabilizer are substantially free from the offensive odour typically associated with mercaptans and are protected during processing by the degradation products of the latent (i.e. blocked) mercaptan which include a free mercaptan. The free mercaptan thus released enhances the activity of metallic-based heat stabilizers such as zinc carboxylates and organotin carboxylates and mercaptides in the polymer composition. Other products of the degradation are believed to include carbocations of the blocking moiety which are stabilized by a molecular structure in which the electron deficiency is shared by several groups. The latent mercaptan comprises a 2-S-(tetrahydropyranyl)-thioalkanol or a carboxylic acid ester thereof.

  含有潜伏硫醇热稳定剂的软质和硬质氯乙烯聚合物组合物基本上没有通常与硫醇有关的刺激性气味，并且在加工过程中受到潜伏（即被阻断）硫醇降解产物（包括游离硫醇）的保护。由此释放出的游离硫醇可增强聚合物成分中金属基热稳定剂（如羧酸锌、有机锡羧酸盐和硫醇）的活性。降解的其他产物据信还包括封端分子的碳基，这些碳基通过分子结构得到稳定，在这种结构中，电子缺陷由多个基团共享。潜在硫醇包括 2-S-（四氢吡喃基）硫代烷醇或其羧酸酯。
