TL;DR: In this paper, the transesterification behavior of poly(butylene terephthalate) (PBT)/polycarbonate (PC) blend with the addition of di-n-dodecyl phosphate was studied with differential scanning calorimetry (DSC) and infrared spectroscopy.
Abstract: The transesterification behavior of a poly(butylene terephthalate) (PBT)/polycarbonate (PC) blend with the addition of di-n-dodecyl phosphate was studied with differential scanning calorimetry (DSC) and infrared spectroscopy. The effects of triphenyl phosphate (TPP) and di-n-dodecyl phosphate on the suppression of transesterification were compared. The differences in the crystallization and melting temperatures during the two heating and cooling cycles in the DSC measurements were lower than those of the virgin PBT/PC blend, and di-n-dodecyl phosphate inhibited the formation of a random copolyester but did not suppress the formation of a block copolyester. The crystallization temperature of the PBT/PC blend in the presence of di-n-dodecyl phosphate was higher than that of the blend in the presence of TPP. Di-n-dodecyl phosphate was thus more effective than TPP in the inhibition of transesterification between PBT and PC. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008.

TL;DR: In this paper, a method for preparing a polymer resin grafted with triphenyl phosphate is provided to solve the problem related to the complicated conventional process, and to simplify the extrusion and injection processes of a polymer resin blend using triphensyl phosphate.
Abstract: A method for preparing a polymer resin grafted with triphenyl phosphate is provided to solve the problem related to the complicated conventional process, and to simplify the extrusion and injection processes of a polymer resin blend using triphenyl phosphate. A method for preparing a polymer resin grafted with triphenyl phosphate comprises the steps of: dissolving a polymer resin having butadiene residues and triphenyl phosphate in an organic solvent; and introducing a radical reaction catalyst thereto to allow grafting of triphenyl phosphate to the butadiene residues. The polymer resin having butadiene residues includes at least one resin selected from a butadiene resin, acrylonitrile-butadiene-styrene resin and high-impact polystyrene resin.

TL;DR: In this paper, a simple and highly efficient method for producing a mixture of high-purity o-biphenyl diphenyl phosphate and triphenyl phosphoric acid was proposed.
Abstract: PROBLEM TO BE SOLVED: To provide a simple and highly-efficient method for producing a mixture of high-purity o-biphenyl diphenyl phosphate and triphenyl phosphate. SOLUTION: The method comprises a step(A1) of conducting a reaction between 1 equivalent of phosphorus oxychloride and 2.3-2.8 equivalents of phenol in the presence of a Lewis acid and a step(B1) of conducting a reaction between the resulting product and o-phenylphenol. Another version of the method comprises a step(A2) of conducting a reaction between 1 equivalent of o-phenylphenol and 2.5-4 equivalents of phosphorus oxychloride in the presence of a Lewis acid and a step(B2) of conducting a reaction between the resulting product and phenol.
