TL;DR: In this paper, a novel environment-friendly flame-retarded unsaturated polyester resin resin and a preparation method for its preparation was proposed. But the method is not suitable for use in vehicles, constructions and electrical appliances.
Abstract: The invention relates to a novel environment-friendly flame-retarded unsaturated polyester resin and a preparation method thereof The resin can be used in vehicles, constructions, electrical appliances and other glass fiber reinforced plastic parts requiring flame retardancy In the environment-friendly flame-retarded unsaturated polyester resin, bibasic alcohol and dibasic acid or estolide are condensed into unsaturated polyester; the unsaturated polyester resin contains solid reactive phosphorus flame retardant and liquid phosphonium flame retardant, and the content of phosphorus element in the resin is not less than 4 percent of gross mass, wherein the reactive phosphorus flame retardant can be one or two of hydroxyphenylphosphinyl-propanoic acid and hydroxyphenylphosphinyl-ethanoic acid; and the liquid phosphonium flame retardant can be one or more of triethyl phosphate, triphenyl phosphate and dimethyl methyl phosphonate Each substance in the resin can be directly melted and polymerized without a catalyst; the product does not require separating solvent, does not have the problem of environmental pollution, and reduces the production cost; and the flame retardant can be easily obtained without adding new equipment

TL;DR: In this article, trialkyl phosphates (3 mol) form a hydrogen-bonded complex with B-trichloroborazole (1 mol), and at 100°, this gives alkyl chloride and a solid borazoles system with -OP(: O)(OR)2 structure attached to each boron atom.
Abstract: Trialkyl phosphates (3 mol.) form a hydrogen-bonded complex with B-trichloroborazole (1 mol.), and at 100°, this gives alkyl chloride and a solid borazole system with -OP(: O)(OR)2 structure attached to each boron atom. At about 200°, trialkyl phosphate is eliminated, and borazole rings appear to become attached by the structure -O.P(: O)(OR).O-. Further polycondensation occurs at ∼500–800°, to give an infusible, insoluble and hydrolytically stable inorganic polymer containing boron, nitrogen and phosphorus.
Related observations with N-methyl- and N-phenyl-B-trichloroborazoles are recorded. Equimolal systems, and dialkyl hydrogen phosphite-trichloroborazole systems are described.
Triphenyl phosphate reacted differently with B-trichloroborazole, but did not react at all with N-trimethyl-B-trichloroborazole.
Techniques of gas chromatography, infra-red spectroscopy and thermogravimetric analysis were used.

TL;DR: In this paper, the effect of triaryl phosphate on the flame retardancy of PPO-HIPS in conjunction with zinc and zinc borate was studied, and the results showed that triaryl phos phate may sequester triaryl pyrophate and thus eliminate its vapor phase activity.
Abstract: Samples of m-PPO (virgin and flame retarded) and high impact polystyrene blended with zinc and zinc borate (2ZnO·3B2O3·3.5H 2O), were pre pared. The effect of triaryl phosphate on the flame retardancy of PPO-HIPS in conjunction with zinc and zinc borate was studied.For polystyrene zinc borate shows some reduction in smoke generation. Zinc, however does not show any effect on smoke generation for high impact polystyrene. Triphenyl phosphate shows minimal flame retardancy in HIPS which is not enhanced by zinc.Addition of zinc gives an increase in oxygen index for FR m-PPO, whereas zinc borate decreases the OI values. Zinc borate may sequester triaryl phos phate and thus eliminate its vapor phase activity. Zinc borate shows a signifi cant reduction in smoke generation and rate of heat release for m-PPO.

TL;DR: In this paper, the subject composition is obtained by formulating an organic phosphorus compound of the formula (R to R are each 6-20C aromatic hydrocarbon residue) with a polyester resin for a transparent molding product (e.g. polyethylene terephthalate modified by 1,4cyclohexanedimethanol).
Abstract: PROBLEM TO BE SOLVED: To obtain the subject composition having flame resistance imparted without preventing the transparency of a polyester resin for a transparent molding material by formulating a an organic phosphorus compound having a specific structure with the polyester resin. SOLUTION: The subject composition is obtained by formulating (B) an organic phosphorus compound of the formula (R to R are each 6-20C aromatic hydrocarbon residue) with (A) a polyester resin for a transparent molding product (e.g. polyethylene terephthalate modified by 1,4-cyclohexanedimethanol). The component B is preferably triphenyl phosphate, tricresyl phosphate and tris(2,6-dimethylphenyl) phosphate. The component B is preferably formulated in an amount of 0.5-20 pts.wt. based on 100 pts.wt. component A.
