Title: Innovations of Eduardo M Valcarce
Introduction
Eduardo M Valcarce is a prominent inventor based in South Hadley, MA, known for his contributions to the field of polymer science. With a focus on innovations in ABS (Acrylonitrile Butadiene Styrene) polymers, Valcarce has secured two patents that reflect his expertise and dedication to advancing polymerization processes.
Latest Patents
Valcarce's latest patents highlight his innovative approach to mass polymerization processes for ABS polyblends. The first patent describes an ABS polymer comprising a graft copolymer formed by graft polymerizing styrene and acrylonitrile monomers onto a low gel diene rubber. This method results in a copolymer where the graft copolymer is uniformly dispersed, and the diene rubber constitutes 3 to 25% by weight with a polymerized acrylonitrile content ranging from 27 to 40% by weight.
His second patent outlines a continuous mass polymerization process wherein an alkenyl aromatic monomer, combined with diene rubber, is continuously charged to a reactor alongside a feed-stream of an alkenyl nitrile monomer. The reactor's stirring maintains a uniform composition within the reaction mixture, operating at a steady state polymer solids level that allows the diene rubber to be dispersed into particles of about 0.1 to 10 microns. This innovative process ensures the continuous removal of a partially polymerized reaction mixture, ultimately resulting in the recovery of high-quality ABS polymer.
