This invention is directed to a non-halogen flame retardant thermoplastic molding composition having in combination a high molecular weight linear polyester and a non-halogen flame retardant. The flame retardant may be either a copolymer of polyetherimide-organopolysiloxane or a blend thereof with a polyphenylene sulfide, and/or a polyetherimide. The molding composition of the invention may also contain a filler.

Halogen-free flame retardant ternary blends

Disclosed are flame retardant poly(butylene terephthalate) resins comprising:

Flame retardant polyester blends

Flame retardant polyester compositions exhibiting good processability comprising at least one polyester resin and a flame retardant additive comprising a halogenated polycarbonate resin and an antimony compound in a polyetherimide ester elastomer resin carrier.

Flame retardant compositions

This invention relates to thermoplastic molding compositions, particularly thermoplastic polyesters, having incorporated therein a fluorinated polyolefin to improve wear resistance. More particularly, disclosed are polyester compositions having improved wear resistant good properties comprising a polyester resin, most preferably a poly(butylene terephalate) resin; a fluorinated polyolefin compound and a hindered phenolic compound and an ester compound, the last two components serving as a migrator package that serves to push a disproportionate amount of the fluorinated polyolefin within the subsurface of the resulting composition to thereby augment the wear resistant effect of the fluorinated polyolefin.

Polyester compositions having improved wear characteristics

Novel thermoplastic elastomeric molding compositions having excellent physical properties, which comprise a polyetherimide ester elastomer modified with a modifier composition comprising (i) at least one olefin acrylate copolymer; or (ii) at least one ethylene vinyl acetate copolymer; or a combination of (i) and (ii).

Plasticized polyetherimide ester blends

Disclosed are thermoplastic polyester composition that display increased resistance to warpage. The compositions are comprised of at least one polyester resin modified with a warpage control agent, said warpage control agent being a high molecular weight polyetherimide ester elastomer. The resulting composition is preferably reinforced with glass fibers.

Warpage controlled polyesters

The melt flow of polycarbonate resin molding compositions is improved by the addition of an ethylene-vinyl acetate copolymer, without adversely affecting the impact strength of articles molded from the improved composition.

Moldable polycarbonate resin and copolyester-carbonate compositions of

Ternary polycarbonate blends

A composition comprising an admixture of:

Binary polycarbonate blends

A composition comprising an aromatic polycarbonate in admixture with a diatomaceous earth, the said diatomaceous earth having a major quantity of cristabolite, the quantity of diatomaceous earth such that the kinetic coefficient of friction is substantially decreased when a self supporting film is prepared from the composition.

Polycarbonate resins containing diatomaceous earth

Low gloss, flame reterdant, impact resistant polycarbonate composition

Thermoplastic molding composition of a polycarbonate and a linear low density polyethylene wherein a C.sub.4 -C.sub.7 alpha-olefin is the comonomer.

Composition

A resin composition exhibiting improved resistance to environmental stress crazing and cracking comprising:

Polycarbonate resin blends exhibiting improved resistance to stress

Articles of blow-molded polycarbonate resins are described, having improved flexural modulus. The method of improvement comprises the incorporation of mica particles or glass fiber into the blow-moldable resin as a reinforcing filler. Advantageously the incorporation does not significantly adversely affect the blow-moldability of polycarbonate resins.
