Abstract: A polyester molding composition which includes the presence of gloss reducing amounts of PET, polyester containing ionomeric groups, or mixtures thereof in a PBT/styrenic impact modifier blend for providing low gloss on a textured surface.

Abstract: A halogen-free, flame retardant polyester composition comprises, based on the total composition,

Abstract: A polyketone composition consisting of a blend of a polyketone and glass fibers having a coating composition thereon having an acrylic functionality. The molded articles of the above composition have improved tensile strength and impact resistance. The coating composition may consist of styrene-acrylonitrile copolymer or blends thereof.

Abstract: A process for preparing a polymer composition useful as a prepreg comprises (a) melt-mixing at least one thermoplastic polymer above the glass transition temperature or melt temperature of the thermoplastic polymer with either (i) an uncured epoxy resin or (ii) an epoxy curing agent or a catalyst; (b) melt-mixing above the glass transition temperature or melt temperature of the thermoplastic polymer, the other of (i) an uncured epoxy resin or (ii) an epoxy curing agent or a catalyst to form a substantially uncured but essentially curable and/or polymerizable composition; (c) optionally forming a shaped product from the melt-mixed composition of (b); and (d) fast-curing and/or fast-polymerizing the optionally formed shaped product.

Abstract: UV-stabilized or other modified polycarbonates are prepared by combining polycarbonate, a radical polymerization initiator and a UV-stabilizer-molecule or other additive such as a flame retardant or IR additive containing a reactive group susceptible to radical attack in a melt. In the melt, the UV-stabilizer or other additive is graft polymerized to the polycarbonate to form a modified polycarbonate. The method can be practiced using bis-phenol-A (BPA) polycarbonates, soft-segment polycarbonates and high heat polycarbonates. The reaction may be performed in an extruder.

Abstract: Flame retardant compositions comprising a polymer of carbon monoxide, and at least one olefin, and a flame retarding quantity of a melamine compound.

Abstract: An aliphatic ketone polymer composition having during melt processing improved melt stabilization against significant cross linking and reduced discoloration wherein the composition has in addition to the aliphatic ketone polymer an additive stabilizer comprising a polyol such as sorbitol and an aluminum hydroxide, or an alumina hydrogel, or decomposition products thereof such as pseudo-boehmite. The additive is present in an amount of about 0.01 to about 10.0 weight % based on the weight of ketone polymer and additive.

Abstract: Disclosed are blends of polyesteramides and polyester resins, optionally with polycarbonates, as well as methods for preparing said blends thereof. Preferred polyesteramides are those comprising amide units of formula (I): ##STR1## and ester units of formula (II): ##STR2## wherein the ratio of (I) to (II) is at least 1:1, and more preferably wherein at least 80% of the units of formula (I) are separated by at least one of the units of formula (II).

Abstract: The invention relates to polymer mixtures which comprise an aromatic polycarbonate, a polybutylene terephthalate and a polyalkylene glycol. Due to the presence of the polyalkylene glycol a good lacquer bonding is obtained when lacquer systems on the basis of water are used.

Abstract: The invention relates to polymer mixtures which comprise a polybutylene terephthalate, an aromatic polycarbonate, and a dialkyl silicone fluid. Due to the presence of the dialkyl silicone fluid compound a good lacquer bonding is obtained.
