Frame-retardant styrene resin composition having excellent shock resistance

Abstract: PURPOSE:To obtain a styrene resin composition having both high flame retardancy and high shock resistance, even when the amount of flame retardant is reduced, by further adding ammonium sulfate to a rubber-modified styrene resin, polyphenlene ether and a phosphorus-containing flame retardant. CONSTITUTION:The subject flame-retardant styrene resin composition of high shock resistance is prepared by combining 100 pts.wt. at total of (A) a rubber- modified styrene resin such as shockresistant polystyrene, ABS resin and (B) 10 to 30 pts.wt., preferably 10 to 25 pts.wt. of a polyphenylene ether, preferably poly(2,6-dimethyl-1,4-phenylene ether) of 0.2 to 0.7 dl/g intrinsic viscosity, with (C) 1 to 30 pts.wt. of ammonium sulfate (when needed, surface-treated with higher fatty acids, (D) 1 to 30 pts.wt. of red phosphorus (when needed, surfacecoated with metal hydroxide) and/or an organophosphorus compound such as methyl neopentyl phosphite or triphenyl phosphate.

Synthesis and Properties of New Poly( Amide-Imide)s Based on Imide Dicarboxylic Acid

Abstract: Two kinds of imide dicarboxylic acid monomers, 4,4'-bis(trimellitimido) diphenyl ether Ⅰ and p-trimellitimido-benzoic acid Ⅱ were successfully synthesized from 4,4'-diaminodiphenyl ether and p-aminobenzoic acid with trimellitic anhydride respectively.and used to synthesize a series of new aromatic poly(amide-imide)s (PAIs) by the tri-phenyl phosphite-activated polycondensation method. The preparation of PAIs was carried out using triphenyl phosphate and pyridine symtem. The PAIs had inherent viscosities of 0.55–1.46 dL g-1. PAI films were obtained by casting their N-Methyl-2-pyrrolidone (NMP) solution. Their cast films had tensile strengths ranging from 37.4 to 83.9 MPa. The glass-transition temperatures (measured by differential scanning calorimetry) were in the range of 265-310°C. According to thermogravimetric analysis, the polymers were fairly stable up to temperature around 420°C, and 10% weight losses in the temperature range of 474-550°C in nitrogen, that showed good thermal stabilities of these polymers.

High-gloss fiber-added PC (polycarbonate) composite material

Abstract: The invention provides a high-gloss fiber-added PC (polycarbonate) composite material. The high-gloss fiber-added PC composite material is prepared from raw materials in parts by weight as follows: 40-75 parts of PC, 10-40 parts of modified short glass fibers, 2-15 parts of phosphate ester, 1-6 parts of an MBS flexibilizer, 0.1-2 parts of a dispersing agent and 1-10 parts of titanium dioxide, wherein the modified short glass fibers are grafted with modified polyphenylene sulfide, and modified polyphenylene sulfide is sulfonated polyphenylene sulfide grafted N-[tris(hydroxymethyl)methyl]acrylamide; phosphate ester comprises one or more of triphenyl phosphate, resorcinol bis(diphenyl phosphate), bisphenol A bis(diphenyl phosphate) and resorcinol bis-2,6-dimethylphenyl phosphate.
