Electronic components can be encapsulated with a poly(arylene sulfide) composition containing a mercaptosilane such as, for example, 3-mercaptopropyltrimethoxysilane.

Encapsulation of electronic components with poly(arylene sulfide)

Zinc oxide is used in poly(arylene sulfide compositions to improve encapsulation properties and to inhibit color shift. The invention includes electronic components encapsulated with poly(arylene sulfide) compositions containing zinc oxide.

Zinc oxide in poly(arylene sulfide) compositions

Polyamide and polyacrylamide are useful as mold corrosion inhibitors when incorporated into a poly(arylene sulfide).

Mold corrosion inhibitors

Poly(arylene sulfide) compositions are disclosed having a combination of good cracking resistance and electrical insulation resistance. Such compositions have a variety of uses including uses in molded electrical components.

Poly(arylene sulfide) composition with improved insulation resistance

Electronic components are encapsulated with a calcium silicate-containing poly(arylene sulfide) composition. The composition can also contain a filler such as talc or silica and an organosilane such as 3-mercaptopropyltrimethoxysilane.

Encapsulation of electronic components with calcium silicate-containing

A composition of matter comprising poly(arylene sulfide), fiberglass, and calcium sulfate. A method for producing compositions that is compared with compositions outside of this invention upon molding provide improved insulation resistance and improved surface gloss by admixing calcium sulfate having an average particle size in a range of about 0.5 micron to about 5 microns with poly(arylene sulfide) and fiberglass.

Arylene sulfide compositions containing calcium sulfate

A thermosetting molding composition containing unsaturated polyester and carboxy-containing rubber exhibit improved surface gloss of molded articles when the composition further contains an unsaturated ester/potassium salt of phosphoric acid, such as potassium oleyl phosphate.

Polyester/carboxy-rubber molding composition containing potassium

In polyamide compositions containing the reaction product of (1) a block copolymer of propylene oxide, ethylene oxide and an alkylene diamine and (2) a dicarboxylic acid ester in an amount sufficient to provide improved antistatic characteristics to the polyamide, the apparent dyeability can be increased by including in said polyamide composition a sufficient amount of at least one zinc dihydrocarbyl dithiophosphinate.

Dyeable polyamides containing an antistatic agent

In polyamide compositions containing the reaction product of (1) a block copolymer of propylene oxide, ethylene oxide, and an alkylene diamine and (2) a dicarboxylic acid ester in an amount sufficient to provide improved antistatic characteristics to the polyamide, the apparent dyeability can be increased by including in said polyamide composition a sufficient amount of at least one zinc sulfinate of the formula:

Antistatic dyeable polyamide composition

Homopolymers and copolymers of 1-olefins are protected against the deleterious effects of ultraviolet light by incorporating therein an additive system consisting of a nickel carboxylate and a piperidine derivative in an amount sufficient to prevent such deterioration.

Stabilization of olefin polymers

A mixture of a nickel amine complex and a hydroxyl substituted phenyl benzoate that is unusually effective as an ultraviolet light stabilizer for .alpha.-olefin polymers.

Ultraviolet light stabilized .alpha.-olefins

Ultraviolet light stabilizers for polymers derived from unsaturated monomers comprising mixtures of hydroxy-substituted phenylbenzoates, nickel ketoximes and hindered phenols are described.

Ultraviolet light stabilizing system

Alpha-olefin polymers made dyeable by the addition of a mixture of a nickel compound and an ester of terephthalic acid.
