TL;DR: In this article, a flame retardant for laminates, formed by adding an additive type flame retardants to a halogenated epoxy compound having at least one epoxy group in the molecule or a reaction product thereof with a Halogenated bisphenol A and adjusting the pH of the obtained composition to a value in the range of 5-7.
Abstract: PURPOSE:To form a flame retardant which can form a resin composition having a long pot life when mixed with a resin for laminates, has good compatibility with a resin and can give flame retardancy to the obtained laminate without detriment to its properties, by adding an additive type flame retardant to a halogenated epoxy resin and adjusting the pH of the obtained composition to a specified value. CONSTITUTION:A flame retardant for laminates, formed by adding an additive type flame retardant to a halogenated epoxy compound having at least one epoxy group in the molecule or a reaction product thereof with a halogenated bisphenol A and adjusting the pH of the obtained composition to a value in the range of 5-7. In adjusting the pH, an organic acid such as p-toluenesulfonic acid, benzoic acid or maleic acid is used. Examples of the additive-type flame retardants include triphenyl phosphate, its derivatives and halogenated diphenyl ethers.

TL;DR: An integrated study regarding the occurrence and fate of eleven organophosphate esters (OPEs) was conducted at two wastewater treatment plants (WWTPs) in the area of Thessaloniki, Greece as discussed by the authors .
Abstract: An integrate study regarding the occurrence and fate of eleven organophosphate esters (OPEs) was conducted at two wastewater treatment plants (WWTPs) in the area of Thessaloniki, Greece. Both plants employed conventional activated sludge process whereas as last treatment step the first unit use chlorination and the second one ozonation. OPEs were determined in dissolved fraction, total suspended solids and sludge from various treatment stages of WWTPs. Tris (2-butoxyethyl) phosphate (TBOEP), tris (1-chloro-2-propyl) phosphate (TClPP) and triphenylphosphine oxide (TPPO) were the most abundant compounds in influent and treated effluent. Triphenyl phosphate (TPHP) was also abundant in suspended solids and sludge. Total concentrations of ∑11OPEs ranged from 2144 to 9743 ng L-1 in influents, 1237-2909 ng L-1 in effluents and 3332-14294 ng g-1 dw in sludge. Removal rates from 55% to 80% were observed for most OPEs, whereas chlorinated OPEs, especially for tris(2-chloroethyl) phosphate (TCEP) exhibited low removal efficiency. Mass balance analysis showed that biodegradation was the dominant removal mechanism contributing up to 85%. Sorption onto sludge was also relevant removal pathway for most compounds. Emissions of OPEs through effluents and sludge did not pose considerable risk to the aquatic and terrestrial environment.

TL;DR: In this article, a laminating resin composition having excellent low-temperature punchability and heat-resistance was obtained by compounding a benzoguanamine-modified phenolic resin with a phthalic acid ester as a plasticizer and a phosphoric acid esters as a flame retardant.
Abstract: PURPOSE:To obtain a laminating resin composition having excellent low- temperature punchability and heat-resistance by compounding a benzoguanamine- modified phenolic resin with a phthalic acid ester as a plasticizer and a phosphoric acid ester as a flame retardant and a plasticizer. CONSTITUTION:The objective lamination resin composition having excellent punchability and heat-resistance and useful for the production of a copper-clad laminate giving electronic devices having high reliability can be produced by compounding (A) a benzoguanamine-modified phenolic resin having a modification degree of 10-70wt.% and produced by reacting phenol with benzoguanamine and formalin with (B) a phosphoric acid ester (e.g., triphenyl phosphate or cresyl diphenyl phosphate) and (C) a phthalic acid ester (e.g., dioctyl phthalate or n-dioctyl phthalate) at a weight ratio (B/C) of 95/5-50/50 and, as necessary, adding (D) other additives and fillers to the mixture.
