Abstract
Novel compositions are disclosed which include a polyphenylene ether resin and an alkenyl aromatic resin modified with an EPDM rubber. Also included with the scope of this invention are reinforced and flame-retardant compositions of said polyphenylene ether resin and said alkenyl aromatic resin modified with an EPDM rubber.
Claims9
A thermoplastic molding composition which comprises:
- a. from 20-65% by weight of a polyphenylene ether resin and
- b. from 35-80% by weight of an alkenyl aromatic resin that is modified with a rubbery interpolymer of a mixture of monoolefins and a polyene by polymerizing an alkenyl aromatic monomer in the presence of said rubbery interpolymer.
A thermoplastic molding composition which comprises:
- a. from 20-65% by weight of a polyphenylene ether resin and
- b. from 35-80% by weight of an alkenyl aromatic resin that is modified with a rubbery interpolymer which comprises 10-90 mole percent of ethylene, 10-90 mole percent of an alpha olefin having from 3-10 carbon atoms and from 0.1-10 mole percent of a polyene that is a non-conjugated cyclic or open-chain diene that has from 5-10 carbon atoms by polymerizing an alkenyl aromatic monomer in the presence of said rubbery interpolymer.
