A meta- or para-compound of the formula:
wherein: X⊖ is an anion selected fromthe group consisting of R4OSO3⊖ Cl⊖, Br⊖ and ⊖;
wherein: n is 2 or 3;
R1, R2 and R3 which may be the same or different, are lower alkyl; and
R4 is lower alkyl or allyl.
Also disclosed is a method of making the compound by reacting meta- or para-isopropenyl-a,a-dimethylbenzyl isocyanate with either an amino alcohol or a dialkylamino- ethyleneamine, and quaternizing the reaction product with an alkylating agent. The compound may be polymerized with a co-monomer such as acrylamide to yield water-soluble cationic polymers for use in water clarification, flocculation, and hair spray applications.
式中的元化合物或对位化合物:
其中X⊖ 是选自由 R4OSO3⊖、Cl⊖、Br⊖ 和 ⊖ 组成的组的阴离子;
其中:n 为 2 或 3;
R1、R2 和 R3 可以相同或不同,均为低级烷基;以及
R4 是低级烷基或烯丙基。
本发明还公开了一种制造该化合物的方法,该方法是将偏异丙烯基或对偏异丙烯基-a,a-二甲基苄基异氰酸酯与氨基醇或二烷基氨基乙烯胺反应,并用烷基化剂对反应产物进行季铵化。该化合物可与丙烯酰胺等共聚单体聚合,生成水溶性阳离子聚合物,用于水澄清、絮凝和喷发。
