Abstract
A curable thermoplastic elastomeric blend comprising: (a) from 15 to 60 weight percent of a polyalkylene phthalate polyester polymer or copolymer and; (b) from 40 to 85 weight percent of a poly(meth)acrylate or polyethylene/alkyl (meth)acrylate rubber in combination with an effective amount of peroxide free-radical initiator and an organic multiolefinic coagent to cross-link which upon extrusion or injection molding dynamically cross-link producing a melt processible thermoplastic elastomeric composition having a polyalkylene phthalate polyester polymer or copolymer continuous phase and of a cross-linked polyacrylate or polyethylene/acrylate rubber dispersed phase. Such compositions are useful in the manufacture of rubber parts having excellent resistance to lubricating oils and greases.
