TL;DR: In this paper, the authors presented a method to obtain the subject pellet comprising polyphenylene ether or polycarbonate resin and a specific phosphate ester, low in load deflection temperature, easy in extrusion molding processing, excellent in handleability, and capable of imparting flame retardancy to the resin materials.
Abstract: PURPOSE:To obtain the subject pellet comprising a polyphenylene ether resin, etc., and a specific phosphate ester, low in load deflection temperature, easy in extrusion molding processing, excellent in handleability, and capable of imparting flame retardancy to the resin materials. CONSTITUTION:This pellet comprises (A) a polyphenylene ether resin or a polycarbonate resin and (B) a phosphate ester of the formula (Q1 to Q4 each is a 1-6C alkyl; R1 to R4 each is H, methyl; (n) is >=1; n1, n2 are each 0-2; m1 to m4 each is 0-3) (e.g. the ester of bisphenol A bound two or more triphenyl phosphate molecules, etc.,) and has a load deflection temperature of 120 deg.C under a flextural stress of 18.5kgf/cm . The pellets are blended with (C) a thermoplastic resin (preferably a styrenic resin) and subsequently melt-kneaded to obtain the flame-resistant resin material.

TL;DR: In this article, the interaction between poly(bisphenol A carbonate) (PBAC) and phosphorus compounds such as triphenylphosphine oxide (TPPO),triphenyl phosphate (TPP), and resorcinol bis(diphenyl phosph) (RDP) was clarified.
Abstract: To clarify the interaction between poly(bisphenol A carbonate) (PBAC) and phosphorus compounds such as triphenylphosphine oxide (TPPO), triphenyl phosphate (TPP), and resorcinol bis(diphenyl phosphate) (RDP), PBAC was heated in the presence of these phosphorus compounds at 240 °C for 2 h, and the resulting polymers were analyzed by 1H NMR spectroscopy and gel permeation chromatography. When heated in the presence of TPPO, the PBAC sample decomposed extensively, resulting in a substantial decrease in molecular weight. On the other hand, thermal treatment in the presence of the phosphates increased the molecular weight. In both cases the molecular weight distribution became narrower. Thermal treatment of PBAC in the presence of both TPPO and TPP allowed us to control the molecular weight with a narrower distribution. © 2004 Wiley Periodicals, Inc.
