TL;DR: In this article, a thermoplastic resin, a phosphorus-containing flame retardant and a layered silicate in a specified ratio was used to prevent dripping during burning by melt-kneading.
Abstract: PROBLEM TO BE SOLVED: To prevent dripping during burning by melt-kneading a thermoplastic resin, a phosphorus-containing flame retardant and a layered silicate in a specified ratio SOLUTION: 100 ptswt thermoplastic resin (eg polycarbonate resin) having a number-average molecular weight of 5,000-100,000 is mixed with 05-50 ptswt phosphorus-containing flame retardant represented by formula I (wherein R to R are each H or a 1-6 C alkyl; R is a group represented by formula II or III; and n is 0 or 1-4), eg triphenyl phosphate The obtained mixture is mixed with 001-20 ptswt layered silicate (eg modified montmorillonite containing 10meq/100g of intercalated quat organic onium ions (eg dimethyldioctylammonium ions)) having a mean particle diameter of 05-300μm and an average aspect ratio of 80 or above and optionally additives such as a light stabilizer, an ultraviolet absorber, an antioxidant and an antistatic agent, and the resulting mixture is melt-kneaded with eg an extruder to obtain a flame-retardant resin composition

23 May 1996TL;DR: In this paper, a flame retardant polyketone polymer composition is presented, which comprises a bicyclic phosphorus flame- retardant compound, such as one containing one or more pentaerythritol phosphate alcohol moieties.
Abstract: The present invention is a flame retardant polyketone polymer composition which comprises: (a) a bicyclic phosphorus flame retardant compound, such as one containing one or more pentaerythritol phosphate alcohol moieties, as exemplified by bis(pentaerythritol phosphate alcohol) carbonate; (b) an intumescent flame retardant compound containing nitrogen and phosphorus, such as melamine phosphate; and (c), optionally, a monophosphate ester compound to enhance the compatibility of the composition in the polymer substrate, such as a liquid aryl-group containing phosphate ester compound or melamine phosphate, and the monophosphate ester compound is triphenyl phosphate.

TL;DR: In this paper, a polyurethane elastomer including no halogen-containing flame retardant, having excellent flame retardancy and being capable of relatively easily controlled in elasticity, strengths, hardness, etc., was obtained by mixing a specified polyurehane with a phosphorus flame- retardant.
Abstract: PROBLEM TO BE SOLVED: To obtain a polyurethane elastomer including no halogen-containing flame retardant, having excellent flame retardancy and being capable of relatively easily controlled in elasticity, strengths, hardness, etc., by mixing a specified polyurethane with a phosphorus flame retardant. SOLUTION: A mixture comprising 1mol of an at least trifunctional polyol and 2-3mol of a difunctional polyol and having a molecular weight of 1,500-10,000 is mixed with a polyisocyanate in an OH/NCO molar ratio of 1-1.5. The obtained mixture is mixed with 10-70wt.%, in total, phosphorus flame retardant such as triphenyl phosphate or tricresyl phosphate and optionally aluminum hydroxide and/or fine powdery melamine, at most 10wt.% plasticizer and 1-4wt.% weight-reducing agent having a particle diameter of 10-30μm, and the resulting mixture is reacted. The obtained reaction mixture is poured into a preheated mold and cured by reaction to obtain a flame-retardant polyurethane elastomer having a phosphorus content of 3wt.% or above.

TL;DR: In this paper, a mixture comprising 1mol of an at least trifunctional polyol and 1-3mol of a different polyol having a molecular weight of 1,500-10,000 is mixed with polyisocyanate in an OH/NCO molar ratio of 1-1.5.
Abstract: PROBLEM TO BE SOLVED: To obtain a lightweight polyurethane elastomer capable of being relatively easily controlled in elasticity, strengths, harness, etc., by reacting two specified polyols with a polyisocyanate in the presence of a weight-reducing agent. SOLUTION: A mixture comprising 1mol of an at least trifunctional polyol and 1-3mol of a difunctional polyol and having a molecular weight of 1,500-10,000 is mixed with a polyisocyanate in an OH/NCO molar ratio of 1-1.5. The obtained mixture is mixed with 1-4wt.% weight-reducing agent comprising microballoons having a particle diameter of 10-30μm, optionally 10-70wt.% phosphorus flame retardant such as triphenyl phosphate or tricreasyl phosphate and 10-70wt.% plasticizer such as tri-2-ethylhexyl phosphate. The resulting mixture is poured into a preheated mold and cured by reaction.
