METHOD FOR CONTROLLING POLYMER CHAIN SCISSION

摘要

The invention relates to a method for controlling polymer chain scission in an extrusion system, comprising:providing a polyolefin resin having a molecular weight;selecting a melt temperature for an extruder to cause scission of the polyolefin with decrease in molecular weight;melting the polyolefin resin in the extruder at the melt temperature to form a me andforming the melt into a polyolefin product.
