A vulcanized molded article comprising a blend of about 5-90% by weight of a thermoplastic copolyester or block copolyester elastomer and about 95-10% by weight of a vulcanizable synthetic or natural rubber having an improved adhesive property with polyester fibers or fabrics.

Vulcanized elastomeric molded article

An intimate polyblend of about 5-90% by weight of a thermoplastic copolyester or block copolyester elastomer and about 95-10% by weight of a vulcanizable synthetic or natural rubber. The preferred copolyester is a copolyester of polybutylene terephthalate and the prefered block copolyetherester is polybutylene terophthalate-poly (tetramethylene oxide) glycol block copolyester. These polyblends can be vulcanized to elastomeric molded articles which exhibit an excellent oil and oxygen/ozone resistance even at elevated temperatures, a high impact strength, an increased scuff resistance and an improved flexibility at low and high temperatures. The vulcanized molded articles also have an improved adhesive property with polyester fibers or fabrics.

Vulcanizable polyblend

Disclosed is a flame retarding polyester composition comprising a thermoplastic polyester, a polymeric halogen containing a flame retarding agent, and a selected phosphite compound.

Flame retarding polyester composition

A thermoplastic copolyester elastomer which comprises dicarboxylic acid component mainly composed of terephthalic and phthalic acids, wherein the molar ratio of terephthalic acid to phthalic acid is from about 80/20 to 35/65, and diol component mainly composed of 1,4-butanediol. The elastomer has excellent thermal stability and weatherability and can be improved in the elastomeric properties by orientation of polymer molecule before crystallization.

Thermoplastic copolyester elastomer

A thermoplastic resinous composition comprising a blend of:

Thermoplastic resinous composition

A flame retardant, non-dripping, shape-retaining thermoplastic polyester resin is disclosed comprising (a) a linear polyester, (b) a halogenated aromatic compound, (c) a zirconium compound, preferably in combination with antimony trioxide, and (d) a fibrous reinforcing agent.

Flame retardant, non-dripping, shape-retaining polyester molding

Flame-retarding polyamide composition having excellent mechanical and flame retardant properties is disclosed. The composition comprises polyamide, about 3 to 40% by weight of melamine on the basis of the polyamide, and about 0.5 to 20% by weight on the basis of the polyamide and about 2 to 75% by weight on the basis of melamine of a compound represented by a compound selected from the group consisting of the following formulas (I) and (II) ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are the same or different radicals selected from the group consisting of hydrogen, alkyl, alicyclic and aromatic radicals having from 1 to 10 carbon atoms, and from such radicals having a substituent selected from the group consisting of --OH, --COOR' and --CONH.sub.2, wherein R' is aliphatic alkyl group having from 1 to 5 carbon atoms.
