There is claimed herein an aqueous emulsion comprising a functionalized organic polymer formed by mixing (a) a preformed aqueous emulsion comprising water, particles containing a plurality of silanol modified organic polymer molecules dispersed in the water, and a surfactant; (b) a functionalizing silane and (c) a tin catalyst. Depending on reaction conditions, these emulsions are predominantly non-precrosslinked and photocurable compositions that are crosslinked after application in either the wet or dry state.
本发明要求获得一种
水性乳液,该乳液包含官能化有机聚合物,其形成方法为:(a) 预制
水性乳液,包括
水、分散在
水中的含有多个
硅烷醇改性有机聚合物分子的颗粒和表面活性剂;(b) 官能化
硅烷;(c)
锡催化剂。根据反应条件的不同,这些乳液主要是非再交联和光固化组合物,在湿态或干态应用后会发生交联。
