COMPOSITIONS FOR SURFACE TREATMENT, POLYMERS THEREFOR, AND METHOD OF SURFACE TREATMENT

摘要

"Compositions for Surface Treatment, Polymers Therefor, and Method of Surface Treatment" A coating composition is provided which is suitable for treating a surface so as to provide a water-erodible coating thereon. The composition comprises at least one erodible polymer comprising one or more hydrolysable groups selected from sulphonate esters and sulphate esters which in an aqueous environment will generate by hydrolysis corresponding polymer-bound acid groups. The erodible polymers are described in detail and a method of treating surfaces using the compositions is described.
