Appeal No. 1995-2036
Application 07/920,009
23. An improved low-modulus, flexible thermoplastic molding and extrusion
composition having a flexural modulus of about 140,000 or below as determined in
accordance with ASTM D790, comprising;
(a) about 20% by weight of a polyalkylene terephthalate resin;
(b) about 15% by weight of an aromatic polycarbonate resin;
(c) about 60% by weight of a substantially amorphous copolymer resin comprising a
butadiene based core-shelled multiphased composite interpolymer resin;
(d) about 5% by weight of a mold release agent or a stabilizer.
26. An improved low-modulus, flexible thermoplastic molding and extrusion
composition consisting essentially of:
(a) a substantially crystalline linear thermoplastic polyester resin composition;
(b) an amount of a component capable of reducing the flexural modulus of (a) to not
substantially greater than about 140,000 psi, said component comprising a substantially
amorphous copolymer resin.
