Hydrocurable compositions comprise (A) polymer containing plurality of groups of the formula:
where R1 and R2 are alkyl or are alkylene if joined together and m is 2 or 3, and (B) a monomeric or polymeric material containing at least two acryloxy groups. Polymer (A) preferably contains units of a 2,2-dialkyl-1,3-oxazolidinyl alkyl (meth)acrylate. The compositions may be used for coating, impregnating and adhesive purposes and for binding non-woven fabrics. Under anhydrous conditions the two components are unreactive but upon exposure to moisture, such as atmospheric moisture, they react. The reaction may occur under ambient temperature conditions.
水基固化组合物包括 (A) 含有多个式中基团的聚合物:
其中 R1 和 R2 为烷基或连接在一起的亚烷基,m 为 2 或 3,以及 (B) 含有至少两个丙烯酰氧基的单体或聚合物材料。聚合物(A)最好含有 2,2-二烷基-1,3-噁唑烷基(甲基)丙烯酸酯单元。这种组合物可用于涂层、浸渍、粘合和粘合无纺布。在无水条件下,这两种成分不会发生反应,但一旦接触到水分,如大气中的水分,它们就会发生反应。反应可在环境温度条件下发生。
