The present invention relates to a composition comprising the reaction product of thiocyanogen or a thiocyanogen halide and certain α,β-unsaturated ketones, e.g. chloranil, and solutions of the reaction product in an inert solvent. The composition can be prepared by adding to a thiocyanogen or a thiocyanogen halide solution in an inert solvent certain conjugated unsaturated ketones. Unlike the thiocyanogen or thiocyanogen halide solutions, the composition of this invention does not polymerize over an extended period of time. Thus, the product can be packaged and shipped whereas the known thiocyanogen solutions are unstable and must be used within a relatively short period of time before they polymerize and form a brick-red precipitate, thereby becoming inactive.
The composition can be used to treat the surfaces of polymeric articles to provide a more adherent surface for paint.
本发明涉及一种组合物,该组合物包括
硫氰原或
硫氰原卤化物与某些 α,β-不饱和酮(如
氯苯)的反应产物,以及反应产物在惰性溶剂中的溶液。在惰性溶剂中向
硫氰原或
硫氰原卤化物溶液中加入某些共轭不饱和酮,即可制备该组合物。与
硫氰原或
硫氰原卤化物溶液不同,本发明的组合物在较长时间内不会聚合。因此,该产品可以包装和运输,而已知的
硫氰基溶液不稳定,必须在聚合形成砖红色沉淀之前的较短时间内使用,从而失去活性。
该组合物可用于处理聚合物品的表面,为涂料提供附着力更强的表面。
