A composition and method for forming the composition of poly(arylene sulfide) having improved impact strength and crack resistance. The invention involves mixing poly(arylene sulfide) with a polymeric rubber, a metal hydroxide, and a carboxylic anhydride, each in sufficient amounts and in proportions needed to improve impact strength and crack resistance.

Metal hydroxide additives for poly(arylene sulfide)

Poly(arylene sulfide/sulfone) polymers are treated in order to increase melt stability and decrease impurities by contacting the poly(arylene sulfide/sulfone) polymer with a soluble zinc compound and an acidic solution. In one embodiment, the polymer is treated first with the soluble zinc compound, followed by treatment with the acidic solution. In another embodiment, the polymer is treated in one step with a solution comprising a water soluble zinc compound in an acidic solution.

Treatment of polyarylene sulfide/sulfone polymers

A process for preparing arylene sulfide polymers is provided, comprising contacting an initiator compound, a halothiophenol compound, an polar organic compound, and a base. Blends comprising the inventive polymers and polyamides or polyaramides provide improved mechanical properties.

Method of preparing poly(arylene sulfide) polymers, polymers and polymer

Poly(biphenylene sulfide/poly(phenylene sulfide) copolymers are produced by contacting a p-dihalobenzene and a bis-p-halobiphenyl under polymerization condiditons. Additionally a poly(biphenylene sulfide)/poly(phenylene sulfide) copolymer/fiber reinforced composite is provided.

Arylene sulfide copolymer

Low temperature heat curable arylene sulfide copolymer compositions which are particularly suitable for use in coating applications are provided. The compositions basically comprise a first arylene sulfide copolymer having unsubstituted para- and ortho-aromatic sulfide repeating units in the polymer chain, and a second arylene sulfide copolymer having unsubstituted para-aromatic sulfide repeating units and alkyl-substituted aromatic sulfide repeating units in the polymer chain.

Preparation of poly (biphenylene/phenylene) sulfide

Polyethylene terephthalate molding compositions are provided which comprise polyethylene terephthalate, an aliphatic polyester, a warp resisting amount of an arylene sulfide copolymer, filler, and optionally, colorants.

Polyethylene terephthalate compositions with arylene sulfide random

There are provided compositions comprising poly(arylene sulfide), polymeric rubber, polyethylene, and carboxylic anhydride; and methods for making these compositions. Articles produced from the compositions have reduced shrinkage and improved impact strength.

Modified poly(arylene sulfide) composition with improved impact strength

A phenylene sulfide/sulfone polymer with relatively good melt stability and a method of producing such a polymer are provided. A previously produced phenylene sulfide/sulfone polymer is redissolved in N-methyl-2-pyrrolidone to form a solution. This solution is combined with an alcohol to precipitate highly melt stable phenylene sulfide/sulfone polymer in a particulate form. The alcohol has one to four carbon atoms, such as methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, and the like and mixtures thereof.

Melt stable phenylene sulfide/sulfone polymers and method

An improved process for producing biphenylene sulfide comprising reacting difluorobiphenyl with an alkali metal sulfide in a polar organic compound. The resulting polymer has a high melting point and fiber composites formed therefrom have excellent mechanical properties.

Process for producing biphenylene sulfide polymer

Improved coatings derived from arylene sulfide polymers are provided by use of powdered or liquid slurry coating formulations comprising a metal oxide and an arylene sulfide polymer which has an extrusion rate of about 80 to about 400 grams/10 minutes.
