摘要： The present invention is a process for forming an extruded article containing a copolymer of vinylidene chloride and at least one other ethylenically-unsaturated comonomer, said process comprising the step of extruding the copolymer in the presence of (1) at least one gas which is inert with respect to the copolymer and does not plasticize the copolymer; and (2) essentially no gases which are not inert with respect to the copolymer. Vinylidene chloride copolymers extruded according to the process of the present invention have lower metal adhesion and less tendency to contain specks of carbon than do vinylidene chloride copolymer copolymers extruded under an air atmosphere.

摘要： Substantially linear ethylene polymers, e.g., polyethylenes prepared by constrained geometry catalysis (substantially linear ethylene), which are grafted with one or more unsaturated organic compounds containing both ethylenic unsaturation and a carbonyl group, e.g., maleic anhydride, exhibit desirable adhesive properties. These graft-modified substantially linear ethylene polymers also impart desirable compatibility and impact properties to various thermoplastic polymer blends.
