  摘要：

  本文描述了基于对羟基甲苯和二对羟基甲苯的有机硫醇化合物。更具体地说，本发明的化合物是对羟基甲苯和二对羟基甲苯的混合酯，具有至少一个巯基和最好是多个巯基，以及至少一个非巯基含有基团。这些有机硫醇化合物被用于增塑和/或热稳定含卤素聚合物组合物，特别是聚氯乙烯组合物。这些组合物基本上不含或不含金属基稳定剂、路易斯酸和萜类物质。本发明的化合物在通常容易恶化和变色的聚合物中得到理想应用，这种恶化和变色可能发生在聚合物加工过程中或聚合物暴露于某些环境中，并且令人惊讶地还可作为优秀的增塑剂。

  Disclosed are multi-purpose polymers that are the polymerization product of a monomer mixture comprising at least one amino-substituted vinyl monomer; at least one nonionic vinyl monomer; at least one associative vinyl monomer; at least one semihydrophobic vinyl surfactant monomer; and, optionally, comprising one or more hydroxy-substituted nonionic vinyl monomer, crosslinking monomer, chain transfer agent or polymeric stabilizer. These vinyl addition polymers have a combination of substituents, including amino substituents that provide cationic properties at low pH, hydrophobic substituents, hydrophobically modified polyoxyalkylene substituents, and hydrophilic polyoxyalkylene substituents. The polymers provide surprisingly beneficial Theological properties in acidic aqueous compositions, and are compatible with cationic materials. Additionally, this invention relates to the incorporation of a basic material after the addition of an acidic material to reduce the pH of the composition without negatively impacting the viscosity of the composition. The multi-purpose polymers are useful in a variety of products for personal care, health care, household care, institutional and industrial care, and industrial applications.
