you drink me摘要：The extrusion of polymeric materials, especially thermoplastic polymeric materials, requires a number of physical attributes in the polymer to be controlled during extrusion to effect desirable surface characteristics on the extruded polymer. Extrusion additives have been provided for the improvement of the attributes and characteristics. The prent invention describes an additive system for extrudable thermoplastic polymers, extrudable polymer compositions containing the additive system, and extrusion process using polymers containing the additive system of this invention. The extrusion additive of the prent invention compris: (i) a fluorocarbon polymer, (ii) a poly(oxyalkylene) polymer, (iii) magnesium oxide, and (iv) optionally a stabilizer. The extrudable composition of the invention compris: (A) an extrudable polymer (e.g., a predominant amount, such as at least 50 % by weight of solids), and (B) an effective amount of the stabilized processing aid (extrusion additive).
