23 Feb 1984TL;DR: In this article, the triaryl phosphate mixture provides better flame retardancy per unit weight of phosphorous than, for instance, triphenyl phosphate alone or trimesityl phosphate alone, where one or two of the three aryl groups are mesityl and the remaining groups are independently selected from among phenyl and xylyl.
Abstract: Flame retardant admixtures of triaryl phosphates and a resin as well as a process for preparation are described The triaryl phosphate mixture includes at least one phosphate where 1 or 2 of the 3 aryl groups are mesityl and the remaining group or groups are independently selected from among phenyl and xylyl The triaryl phosphate mixture provides better flame retardancy per unit weight of phosphorous than, for instance, triphenyl phosphate alone or trimesityl phosphate alone

TL;DR: In this paper, a 0.1W 0.001wt% org. phosphorus ester is blended with an aliph. polycarbonate polyol to prevent MW from being lowered by prolonged heating.
Abstract: PURPOSE: To prevent MW from being lowered by prolonged heating, by blending a small quantity of an org. phosphorus ester compd. with an aliph. polycarbonate polyol. CONSTITUTION: A 0.1W0.001wt% org. phosphorus ester is blended with an aliph. polycarbonate polyol obtd. by reacting a carbonate component such as dimethyl carbonate or diphenyl carbonate with a diol component such as 1,6-hexanediol or 1,4-butanediol, thus improving thermal stability. Examples of the org. phosphorus esters are org. acidic phosphates such as methyl acid phosphate; org. phosphites such as triphenyl phosphite; and org. phosphates such as triphenyl phosphate.

TL;DR: In this paper, a soft polyurethane foam capable of being bonded with a skin material easily in sufficiently high bonding strength by flame-lamination, easily and economically, by mixing a specific polyol and a specific amount of an aromatic phosphoric acid ester compound to an organic polyisocyanate, etc., and reacting the components with each other.
Abstract: PURPOSE: To obtain a soft polyurethane foam capable of being bonded with a skin material easily in sufficiently high bonding strength by flame-lamination, easily and economically, by mixing a specific polyol and a specific amount of an aromatic phosphoric acid ester compound to an organic polyisocyanate, etc., and reacting the components with each other. CONSTITUTION: The objective soft polyurethane foam can be produced by mixing and reacting (A) a polyol composed of 60W10pts.(wt.) of a di or tri-functional polyester ether polyol and 40W90pts. of a trifunctional polypropylene glycol adduct, (B) 3W20pts. of an aromatic phosphoric acid ester compound (e.g. triphenyl phosphate) as an agent for modifying flame-lamination characteristics, and (C) an organic polyisocyanate, a foaming agent, a foam stabilizer, a catalyst, a flame retardant, a surfactant, etc. USE: An interior material for automobile, furniture, etc. COPYRIGHT: (C)1986,JPO&Japio

TL;DR: In this paper, a Zn alloy for bearings was obtained by adding an org. phosphoric ester in a stage for melting metal consisting of Al, Si, and Zn or further contg.
Abstract: PURPOSE:To obtain a Zn alloy for bearings contg. 4-30% Al, <=10% Cu and uniformly and finely crystallized Si by adding an org. phosphoric ester in a stage for melting metal consisting of Al, Si and Zn or further contg. Cu, and casting the molten metal. CONSTITUTION:In a stage for melting metal consisting of Al, Si and Zn or further contg. Cu, the metal is mixed with the phosphoric ester of an aliphatic or aromatic alcohol and melted, and the molten metal is cast. Trimethyl phosphate, triphenyl phosphate or the like is effectively used as the phosphoric ester. The ester may be dispersed or dissolved in a solvent such as hydrocarbon before the mixing. The amount of the ester to be added is 0.05-1% when expressed in terms of P. The resulting Zn alloy for bearings consists of, by weight, 4-30% Al, 0.5-5% Si, <=10% Cu and the balance Zn.
