发明名称 PROCESS FOR PRODUCING HIGH MELT FLOW POLYMERS
摘要 <p>Disclosed is a process for making polyolefin pellet products that contain at least one unreacted free radical generator which, when heated, undergo chemical degradation producing a low viscosity polymer. The process includes contacting the polyolefin pellet with the at least one free radical generator to coat the pellet, and contacting the coated pellets and at least one unreacted free radical generator at an elevated temperature and for a period of time sufficient for the free radical initiator to soak into the interior of the pellets. The process of the invention enables the production of polyolefin pellets having any desired amount of free radical generator and therefore, production of a desired viscosity, and improves the processability of the polyolefin pellet at customer fabrication facilities to thereby provide superior quality final articles.</p>
