PROCESS FOR MAKING COMPOSITE POLYMER

摘要

An process for producing composite polymeric materials which comprise wood pulp fiber and thermoplastic polymer is provided, comprising the step of decreasing the exit area of the mixing device to 40 to 60% of the cross-sectional area of the mixing device. The wood pulp fiber used is preferably a bleached chemical wood pulp fiber. The process further includes conversion of the composite polymer materials into pellet form.
