Interaction of hydride silica surfaces with N-vinyl-2-pyrrolidone

The solid-phase thermal and catalytic hydrosilylation of N-vinyl-2-pyrrolid one on the surface of hydride silicas has been studied. It was established that thermal polymerization of N-vinyl-2-pyrrolidone occurs as a side react ion during the thermal hydrosilylation of N-vinyl-2-pyrrolidone. It has als o been found that the interaction of silicon hydride groups with water and propan-2-ol, as well as the formation of metallic platinum occur as side re actions during the catalytic hydrosilylation of N-vinyl-2-pyrrolidone on th e surface of hydride silicas. Thermal hydrosilylation of N-vinyl-2-pyrrolid one in the absence of a catalyst and solvent is much preferred for the chem ical bonding of N-vinyl-2-pyrrolidone in the surface layer of hydride silic as.
