TL;DR: In this article, a manufacturing method for a polymer compound having (C) monofluorophosphoric acid structure, the method comprising a reaction process of (A) polymeric compound having hydroxyl group in the molecule with (B) difluoroporic acid or its salt, whereby enhancing the fluorine content of the product.
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method for a polymer compound having (C) monofluorophosphoric acid structure, the method comprising a reaction process of (A) polymer compound having hydroxyl group in the molecule with (B) difluorophosphoric acid or its salt, whereby enhancing the fluorine content of the product. SOLUTION: The method to manufacture the polymer compound having monofluorophosphoric acid structure comprises such a process that (A) the polymer compound having hydroxyl group in the molecule and (B) the difluorophosphoric acid or its salt are put in reaction with each other in a non-protonic solvent consisting of a solvent of one or more of (C) dimethyl sulfoxide, trimethyl phosphate, triethyl phosphate, tripropyl phosphate, tributyl phosphate, and triphenyl phosphate, wherein the polymer compound is structured so that the ratio in the mol number of (B) the difluorophosphoric acid or its salt to (A) the hydroxyl group in the compound having hydroxyl group in the molecule is five or more.

TL;DR: In this article , a case-control study was conducted in Shandong Province, China, where 481 serum samples were collected from patients with thyroid cancer (n = 242) and healthy controls (n= 239) in a hospital.
Abstract: Novel brominated flame retardant (NBFR) and organophosphate ester (OPE) exposure may engender adverse effects on human health. However, present epidemiological information regarding the effects of such exposure is limited and controversial. In this case-control study, 481 serum samples were collected from patients with thyroid cancer (n = 242) and healthy controls (n = 239) in Shandong Province, eastern China. The levels of NBFRs and OPEs, thyroid hormones, and serum lipid parameters were measured in all the participants. Pentabromotoluene, 2,3-dibromopropyl 2,4,6 tribromophenyl ether, decabromodiphenylethane (DBDPE), tris (2-chloroethyl) phosphate (TCEP), and triphenyl phosphate (TPP) were widely detected (detection frequency > 60%) in all the participants. A significantly high risk association was found between exposure of NBFRs and OPEs (namely 1,2,3,4,5-pentabromobenzene, DBDPE, tri-n-propyl phosphate, tri[(2R)-1-chloro-2-propyl] phosphate, tris (1,3-dichloro-2-propyl) phosphate, and tris (2-butoxyethyl) phosphate) and thyroid cancer in both males and females. In the females of the control group, TCEP levels exhibited a significantly positive association with thyroid-stimulating hormone and a negative association with triiodothyronine (T3), free triiodothyronine (FT3), and free thyroxine (FT4) levels. Weighted quantile sum regression evaluated the mixed effects of the compounds on thyroid hormones levels and thyroid cancer. As a result, TPP accounted for the majority of the T3, thyroxine, and FT3 amounts. Our results suggest that NBFR and OPE exposure contributes to alterations in thyroid function, thereby increasing thyroid cancer risk.

TL;DR: In this paper, the authors proposed a title prepreg of high adhesively with both low heat generating and smoking nature even in its burning by incorporating a thermosetting phenolic resin with an epoxy resin NBR and organophosphoric ester.
Abstract: PURPOSE:To obtain the title prepreg of high adhesively with both low heat- generating and smoking nature even in its burning by incorporating a thermosetting phenolic resin with an epoxy resin NBR and organophosphoric ester. CONSTITUTION:The objective prepreg using a matrix resin composition comprising a thermosetting phenolic resin, epoxy resin, acrylonitrile-butadiene rubber and organophosphoric ester >=200 deg.C in boiling point. The NBR is pref. a three- component copolymer having carboxylic component because of enhancing adhesivity, and said organophosphoric ester is e.g., triphenyl phosphate, tricresyl phosphate.
