    Abstract: The present invention is an aqueous dispersion of a stable polynitrile oxide represented by the structure: R-(C≡N-O-)x, whre x is an integer greater than 1, R is an aromatic, aliphatic, or cycloaliphatic group having at least one substituent adjacent to each nitrile oxide group, the substituent characterized by inhibiting dimerization of nitrile oxide, and being non-interfering with a reaction between nitrile oxide groups and unsaturated groups. The present invention is also a method of curing a latex having a polyunsaturated disperse phase, comprising the steps of: a) mixing the latex with a stable polynitrile oxide; and b) removing water form the mixture. The present invention provides a simple means of preparing one-part coating systems that can be cured at room temperature without the release of by-products.

    Abstract translation: 本发明是由以下结构表示的稳定的多腈氧化物的含水分散体:R-(C = NO-)x,其中x是大于1的整数,R是具有以下结构的芳族,脂族或脂环族基团: 与腈氧化物基团相邻的至少一个取代基,所述取代基的特征在于抑制腈氧化物的二聚,并且不干扰腈氧化物基团与不饱和基团之间的反应。 本发明还是一种固化具有多不饱和分散相的胶乳的方法,该方法包括以下步骤:a)将胶乳与稳定的多腈氧化物混合; 和b)从混合物中除去水。 本发明提供了一种制备可在室温下固化而不会释放副产物的单组分涂料体系的简单方法。
