摘要:
The present invention relates to a flame retardant thermoplastic resin composition that contains a phenol resin derivative having good char formability, regardless of the base resin. A flame retardant thermoplastic resin composition according to the present invention comprises (A) 100 parts by weight of a thermoplastic resin as a base resin, (B) about 0.1null100 parts by weight of a phenol resin derivative, and (C) about 0.1null50 parts by weight of a phosphoric acid ester morpholide compound or a mixture of phosphoric acid ester morpholide compounds. Another flame retardant thermoplastic resin composition according to the present invention comprises (A) 100 parts by weight of a thermoplastic resin as a base resin, (B) about 0.1null100 parts by weight of polyphenylene ether, (C) about 0.1null100 parts by weight of a phenol resin derivative, and (D) about 0.1null50 parts by weight of a phosphoric acid ester morpholide compound or a mixture of phosphoric acid ester morpholide compounds. The thermoplastic resin composition containing polyphenylene ether resin may also contain up to 5.0 parts by weight of an anti-dripping agent based on 100 parts by weight of the base resin.
摘要:
The present invention relates to polyphosphate ester morpholides, compositions comprising mixtures thereof and thermoplastic resin compositions containing the polyphosphate ester morpholide composition as a flame retardant. The flame retardant compositions comprise mixtures of polyphosphate ester morpholides which are represented by the following general formula I: 1 in which X is 1 or 2; R1 is a C6-C20 aryl group, an alkyl substituted C6-C20 aryl group or a derivative thereof; R2 is a C6-C30 arylene group, an alkyl substituted C6-C30 arylene group or a derivative thereof; n is the average number of morpholide repeating units, m is the average number of R1 repeating units, and nnullm is 1 to 5. In accordance with the present invention, it is possible to provide a flame retardant thermoplastic resin compositions having improved flame retardancy even when small amounts of the flame retardant are used. The thermoplastic compositions according to the present invention also have a desirable balance of properties such as workability, impact strength, heat resistance, appearance and the like.

摘要:
The present invention relates to a flame retardant thermoplastic resin composition that comprises a polycarbonate resin, a rubber modified styrene-grafted copolymer, a styrene-containing copolymer, a (meth)acrylic acid ester copolymer, a phosphoric acid ester as a flame retardant and a fluorinated polyolefin resin, which does not show coalescence of the domain resin that might be caused by the low viscosity at a high temperature, and poor flame retardancy, weld-line strength and mechanical properties such as impact strength, and which has a good balance of physical properties such as impact strength, heat resistance, heat stability, processability and appearance.
