摘要： The composition of the present invention is a miscible blend comprising a first addition copolymer and a second addition copolymer, each having a weight-average molecular weight of about 30,000 to 100,000 and a number-average molecular weight of about 5,000 to 50,000, and each comprising repeating units of (1) at least one of an aromatic vinyl monomer of the structure, ##STR1## where Ar is phenylene or naphthylene and R.sup.1 and R.sup.2 are H or lower alkyl; and (2) at least one of (a) an acrylic ester of the structure ##STR2## where R.sup.3 is linear or branched C.sub.1 -C.sub.10 alkyl and R.sub.4 is H or lower alkyl, or (b) a divinyl compound of the structure ##STR3## where R.sup.5 and R.sup.6 are H, Cl, or CH.sub.3. The polymer composition comprises a miscible blend of the above-described first and second addition copolymers. The first addition copolymer further comprises repeating units of an acidic vinyl monomer, and the second addition copolymer further comprises repeating units of a basic vinyl monomer. Also in accordance with the present invention, an electrophotographic toner receiver for thermally assisted transfer comprises a substrate having a layer of a thermoplastic polymer composition on the surface thereof. The polymer composition comprises a miscible blend of the above-described first and second addition copolymers. Further in accordance with the invention, a method comprises the non-electrostatically transferring of small toner particles from the surface of a photoconductive element to the described toner receiver.
