A formaldehyde-free latent crosslinking monomer represented by the formula ##STR1## in which R.sup.1 and R.sup.2 are C.sub.1 -C.sub.3 alkyl; R.sup.3 is hydrogen, C.sub.1 -C.sub.3 alkyl, or R.sup.4 --C(O)--; and R.sup.4 is C.sub.1 -C.sub.3 alkyl or C.sub.6 -C.sub.8 aryl, contains an allyl group capable of undergoing addition copolymerization and a dialkoxy ethyl group capable of crosslinking under acidic conditions. The monomer can be copolymerized with comonomers to form emulsion polymers for use as formaldehyde-free binders in nonwoven textiles. Methods for the preparation of the monomer, the polymers, and the nonwoven fabrics are described.
一种无甲醛潜在交联单体,其化学式为##STR1## 其中R.sup.1和R.sup.2为C.sub.1-C.sub.3烷基;R.sup.3为氢,C.sub.1-C.sub.3烷基或R.sup.4 --C(O)--;R.sup.4为C.sub.1-C.sub.3烷基或C.sub.6-C.sub.8芳基,含有能够发生加成共聚反应的烯丙基团和在酸性条件下能够交联的二烷氧基乙基基团。该单体可以与共聚单体共聚形成乳液聚合物,用作无甲醛粘合剂,用于无纺织品。描述了制备该单体、聚合物和无纺织品的方法。
