Various novel acetal- and aldehyde-containing monomers are prepared. They can be polymerized and copolymerized by conventional polymerization techniques. The polymers contain repeating units derived from one or more ethylenically or allylically unsaturated monomers containing an acetal group or aldehyde group and optionally one or more repeating units derived from ethylenically or allylically unsaturated monomers other than the acetal-containing or aldehyde-containing monomer such as ethylene, vinyl acetate, ethyl acrylate, butyl acrylate, 2-ethylhexyl acrylate, hydroxyethyl acrylate, hydroxypropyl acrylate, methyl methacrylate or acrylic acid. Aqueous emulsions of polymers containing the acetal-containing monomers and a hydroxy-containing monomer are useful as binders for nonwoven fabrics.
制备了各种新型含醛单体。它们可以通过传统聚合技术进行聚合和共聚。乙烯、乙酸乙烯酯、丙烯酸乙酯、丙烯酸丁酯、丙烯酸 2-乙基己酯、丙烯酸羟乙酯、丙烯酸羟丙酯、甲基丙烯酸甲酯或丙烯酸。含缩醛单体和含羟基单体的聚合物水乳液可用作无纺布的粘合剂。
