    • Novel copolymerizable esters of cinnamic acid or an .omega.-alkenoic acid of from 4 to 18 carbon atoms, such as undecylenic acid, with certain hydroxyalkane sulfonic acids, such as isethionic acid, are described together with processes of making them and copolymers thereof. These novel copolymerizable esters may be made by reaction of the .omega.-alkenoic or cinnamic acid with the hydroxyalkane sulfonic acid or a sultone, such as propane sultone. These novel ester are useful as copolymerizable surfactants in the emulsion polymerization of ethylenically unsaturated monomers; particularly for the production of self-stabilizing latices of polymeric materials possessing excellent mechanical stability and from which can be deposited films having improved adhesion, pigment wetting and bonding properties and greatly improved resistance to water. They are also useful as comonomers for the production of polymeric materials having sulfonic acid functionality, such as polyelectrolyte materials based on acrylonitrile, vinyl chloride, vinyl acetate, acrylates, methacrylates, styrene, etc.; for example, when used as a comonomer in the production of fibers and films based on the above monomers, they impart improved dye receptivity and anti-static properties to the polymeric fibers and films so made.
    • 将具有4至18个碳原子的肉桂酸或ω-链烯酸(例如十一碳烯酸)与某些羟基烷基磺酸如羟乙磺酸的新型可共聚的酯与其制备方法和其共聚物一起进行了描述。 这些新型可共聚的酯可以通过ω-亚油酸或肉桂酸与羟基链烷酸磺酸或诸如丙磺酸内酯的磺内酯的反应来制备。 这些新型酯可用作烯属不饱和单体的乳液聚合中的可共聚表面活性剂; 特别是用于生产具有优异的机械稳定性的聚合材料的自稳定胶粘剂,并且可以从其中提供具有改进的粘合性,颜料润湿性和粘合性能以及极大改善的耐水性的沉积膜。 它们也可用作生产具有磺酸官能团的聚合物材料的共聚单体,例如基于丙烯腈,氯乙烯,乙酸乙烯酯,丙烯酸酯,甲基丙烯酸酯,苯乙烯等的聚电解质材料; 例如,当在基于上述单体的纤维和薄膜的生产中用作共聚单体时,它们赋予所制成的聚合物纤维和薄膜更好的染料接受性和抗静电性能。
