Abstract:
1. A process for production of an extrudable composition comprising introducing to an extruder a composition comprising: A) a linear low density polyethylene; B) 25-2000 parts per million by weight, based on the total weight of said extrudable composition, of a fluoroelastomer having a Mooney viscosity, measured per ASTM D1646 at 121° C., large rotor, condition ML 1+10 minutes, of 60 to 80; and C) an interfacial agent in an amount no more than a 5:1 weight ratio of interfacial agent to fluoroelastomer; wherein said interfacial agent is selected from the group consisting of i) silicone-polyether copolymers; ii) aliphatic polyesters; iii) aromatic polyesters; iv) polyether polyols and v) poly(oxyalkylene) polymers, with the proviso that at the time when said fluoroelastomer is contacted with said interfacial agent the fluoroelastomer has a weight average particle size greater than 2 microns.
