TL;DR: In this article, a method for preparing polyester resins for a bottle is provided, to increase the intrinsic viscosity of the polyester resin to 0.70-1.0 dl/g and the heat resistant charging temperature of a bottle made by using the resin to 90-95 deg.
Abstract: PURPOSE: A method for preparing a polyester resin for a bottle is provided, to increase the intrinsic viscosity of the polyester resin to 0.70-1.0 dl/g and the heat resistant charging temperature of a bottle made by using the resin to 90-95 deg.C. CONSTITUTION: The method comprises the steps of: polymerizing terephthalic acid or dimethyl terephthalate and ethylene glycol to obtain a linear polyester resin. Preferably 200-750 ppm/PET of a condensation polymerization catalyst, 100-200 ppm/PET of a heat stabilizer, 20-200 ppm/PET of a promoter and 10-100 ppm/PET of a Tin-based compound are used for the method, wherein the condensation polymerization catalyst is selected from the group consisting of antimony trioxide, antimony triacetate, germanium oxide and their mixtures, the heat stabilizer is a phosphorus compound, and the promoter is cobalt acetate. The phosphorus compound comprises trimetal phosphate, triethyl phosphate and triphenyl phosphate.

TL;DR: In this article, the individual and the combined effects of tribromophenyl acrylate and triphenyl phosphate on the oxygen index of UV-curable urethane-acrylate resin have been studied.
Abstract: UV-curable urethane acrylate resin and oligoester acrylate resin have been effectively flame retarded with vinyl-type flame-retardant monomers containing both bromine and phosphorus atoms. Thermogravimetric analysis indicates that the decomposition temperature of flame-retardant monomer is more closely matched to the decomposition temperature of cured oligoester acrylate resin than to that of cured urethane acrylate resin. The efficiency of each flame-retardant monomer in oligoester acrylate resin is higher than in urethane acrylate resin by a factor of ∼ 2.2. The individual and the combined effects of tribromophenyl acrylate and triphenyl phosphate on the oxygen index of UV curable urethane acrylate resin have been studied. The bromine phosphorus synergistic action of the two flame-retardant components is evaluated quantitatively, and a maximum intermolecular bromine phosphorus synergism was observed in a flame-retarded formulation containing a Br/P atom ratio of 2. In the three acrylic monomers containing both bromine and phosphorus atoms, the optimum intramolecular bromine phosphorus synergism was observed at a monomer also containing a Br/P atom ratio of 2.

TL;DR: In this article, eight organophosphorus compounds, trimethyl phosphate (TMP), tributyl phosphite (TBP), triphenyl phosphate (TPP), trimethyl phosphite(TMPI), TMPI, triphenylon phosphoric acid (TPPI), diethyl phosphitic acid (DEPI), and diphenyl phosphoryl chloride (DPPC), were employed as activating agents to prepare activated carbons (AC-OPCs) from lotus stalks.

TL;DR: In this article, the upfield shielding effect is only operative when the carbon atom, situated γ to the exocyclic oxygen, bears at least one hydrogen, and conformational changes about the arylO bond can be monitored via the vicinal 31pOC13C couplings.
Abstract: 13C NMR chemical shifts and 13C31P couplings are reported for triphenyl phosphate and 13 alkyl derivatives. In ortho-alkylated materials, it is found that the upfield γ shielding effect is only operative when the carbon atom, situated γ to the exocyclic oxygen, bears at least one hydrogen. Conformational changes about the arylO bond can be monitored via the vicinal 31pOC13C couplings.

TL;DR: In this paper, the formation of an inclusion complex (IC) between Triphenyl Phosphate (TPP) and β-cyclodextrin (β-CD) will reduce its toxicological effects, while retaining the flame retarding properties of TPP.
