    摘要： A process for impregnating fiber and textile materials with hydrophilic polymers prepared by admixing in a solvent-free system in the presence of a free radical, vinyl polymerization catalyst and reacting a major amount of a water-soluble polymerizable monoester of an olefinic acid having at least one substituted functional group with a minor amount of a polymerizable diester of one of said olefinic acids having at least two esterifiable hydroxy groups, such as 2-hydroxy ethyl methacrylate or hydroxy propyl methacrylate. Suitable crosslinking agents include ethylene glycol dimethacrylate, 1,3butylene dimethacrylate, 1,4-butylene dimethacrylate or other polyfunctional monomeric esters. The fiber and textile materials can be impregnated from liquid casting syrups, from alcoholic solution of the polymer, or from aqueous emulsion of the polymer. The impregnated polymer exhibits an elongation of about 5 percent or less in the dry state.

    摘要翻译： 一种用亲水聚合物浸渍纤维和纺织材料的方法，其通过在无溶剂体系中在自由基，乙烯基聚合催化剂的存在下混合而制备，并使大量至少具有至少一种的烯属酸的水溶性可聚合单酯 一个取代的官能团，其中少量的具有至少两个可酯化羟基的所述烯属酸之一的可聚合二酯如甲基丙烯酸2-羟乙酯或甲基丙烯酸羟丙酯。 合适的交联剂包括乙二醇二甲基丙烯酸酯，1,3-丁二醇二甲基丙烯酸酯，1,4-丁二醇二甲基丙烯酸酯或其它多官能单体酯。 纤维和纺织材料可以从液体浇铸糖浆，聚合物的醇溶液或聚合物的水性乳液中浸渍。 浸渍的聚合物在干燥状态下表现出约5％或更低的伸长率。

    摘要： A HYDROPHILIC CROSS-LINKED POLYMERIC COMPOSITION HAVING VITAMINS ABSORBED THEREIN. THE HYDROPHILIC CROSS-LINKED POLYMER IS PREPARED BY ADMIXING IN THE SOLVENT-FREE STATE A MAJOR AMOUNT OF A WATER-SOLUBLE POLYMERIZABLE MONESTER OF AN OLEFINIC ACID HAVING AT LEAST ONE SUBSTITUTED HYDROPHILIC FUNCTIONAL GROUP WITH A MINOR AMOUNT OF A GREE RADICAL, VINYL POLYMERIZATION CARALYST IN AN ANAEROBIC ATMOSPHERE AND HEATING FROM AMBIENT TEMPERATURES TO ABOUT 80*C. UNTIL THE SAIF MONOMER IS WATER-INSOLUBLE, COOLING SAID RESULTING MIXTURE TO AMBIENT TEMPERATURE AND ADDING A MINOR AMOUNT OF A POLYMERIZABLE DIESTER OF ONE OF SAID OLEFINIC ACIDS HAVING AT LEAST TWO ESTERIFIABLE HYDROXY GROUPS ALONG WITH AN ADDITIONAL MINOR AMOUNT OF ONE OF SAID CATALYSTS SUFFICIENT TO FORM A LIQUID CASTING SYRUP ADAPTED TO BE POLYMERIZED IN SITU. POWDERS WHICH MAY BE PRODUCED FROM THE RESULTING PRODUCT ARE MIXED WITH SELECTED VITAMINS WHICH CAN BE RECONSTITUTED IN SOLUTION AT WILL. ALSO, BECAUSE OF THE COMPACT FORM OF THE VITAMIN CARRYING POWDERS ENCAPSULATION MAY BE PERFORMED TO PREVENT DETERIORATION OF THE VITAMIN COMPONENT.
