Abstract

3-(2-oxo-1-pyrrolidinyl)-propylsilane compounds represented by the following general formula (I) are herein disclosed: ##STR1## wherein R.sup.1 and R.sup.2 may be the same or different and each represents a hydrocarbon group having 1 to 4 carbon atoms; and n is an integer ranging from 0 to 2. The propylsilane compounds may be prepared by, for instance, reacting 1-allyl-2-oxopyrrolidine with a hydrogen silane such as trimethoxysilane or trichlorosilane in the presence of a platinum catalyst or further optionally reacting the resulting 3-(2-oxo-1-pyrrolidinyl)-propyl halogenosilane (in the case where a halogenosilane is used) with an alcohol such as methanol. These propylsilane compounds are effective as anti-clouding agent for treating the surface of a variety of substrate.
