Abstract: A single stage process, with recirculation of reactants, is provided herein for making N-vinylpyrrolidone or N-vinyl caprolactam at a high reaction rate and selectivity and at a predetermined conversion per pass. In this process a reaction mixture is formed by saturating a non-aqueous, liquid mixture of recirculating lactam, vinyl lactam and catalyst with acetylene at low temperatures and pressures to provide a high concentration of acetylene in the liquid, pumping the saturated solution into a reactor, reacting the mixture as a single liquid phase, cooling the reaction product, withdrawing a portion of the cooled product, recirculating the rest into the reaction mixture, and continuously feeding additional lactam and catalyst therein.
Abstract: A rheology modifier for use in aqueous or alcoholic compositions includes an aqueous two-phase polymeric composition of by weight, 5-75% of (a) a water-soluble polymer having (b) in situ-formed, substantially water-insoluble resinous particles of said polymer substantially uniformly dispersed therein, and (c) 25-95% of water.
