Application 10/482,217
8) Liao discloses the addition of other additives such as reinforcing
materials (Liao, col. 8, ll. 64-67) and impact modifiers (Liao, col. 9, ll.
21-22).
9) Gallagher discloses flame retardant thermoplastic molding
compositions which include single thermoplastic resins or a
heteropolymer thermoplastic resin blend. According to Gallagher,
suitable thermoplastic resins include, for example, polyesters,
polyethers, polyamides, polyolefins, polycarbonates, including mixtures
of these polymers provided that such mixture constitutes a
heteropolymer blend. Gallagher defines the term "heteropolymer
thermoplastic resin blend" as “a blend of two polymers from differing
classes of polymers, such as blends of the foregoing but excluding
blends of two polymers from within the same class of polymers, e.g.,
polyester/polyester blends, etc. A heteropolymer thermoplastic resin
blend does not, however, exclude blends of two polyesters which are
part of a blend of polymers from different classes, e.g., a blend of
polycarbonate, polybutylene terephthalate and polyethylene
terephthalate.” (Gallagher, col. 2, ll. 46-54). Gallagher specifically
discloses blends of polycarbonate resin with both PBT and PET
(Gallagher, claim 13; Table 1).
10) Gallagher discloses the addition of stabilizers to the compositions
at a level of 0.01-10 weight percent and preferably at a level of from
0.05-2 weight percent. The stabilizers include an effective amount of an
acidic phosphate salt; an acid, alkyl, aryl, or mixed phosphite having at
least one hydrogen or alkyl group; a Group IB or Group IIB metal
