Patent number: 7572862Abstract: The invention relates to a process aid for use in rigid thermoplastic compositions, and especially in rigid polyvinylchloride (PVC) compositions. The process aid is an acrylic terpolymer of methylmethacrylate, butyl acrylate and styrene at an optimal ratio to produce a significant reduction in melt process viscosity. The resulting reduction in extrusion melt torques enables manufacturers of rigid PVC products to have higher throughput production rates.Type: GrantFiled: February 8, 2005Date of Patent: August 11, 2009Assignee: Arkema Inc.Inventors: Mark Lavach, Paul Lavallee, Jason Pomante, Wayne Ranbom, Lisa Rachwal, Stephane Girois
