Abstract: A system and process for injection molding polymer articles is described. The system and process are designed to reduce gate blush. In one embodiment, an injection molding device injects a molten polymer composition into a mold cavity adjacent to an interior curved surface on the mold. The flow of the polymer material is parallel to a line that is tangent to the curved surface.

Abstract: This invention provides a method of initiating chain reaction in a chain reaction medium including (a) a macroinitiator and (b) chain reactants selected from monomers, reactive oligomers, reactive diluents and derivatives thereof and mixtures of the forgoing. The macroinitiator includes a multidentate anchor segment coordinated with a magnetic nanoparticle through more than one bond, and a chain reaction initiator segment bound to the multidentate anchor and providing a weak bond that can be cleaved to initiate a chain reaction. The method further comprises subjecting the chain reaction medium to an alternating current magnetic field to vibrate the magnetic nanoparticle and thereby cleave the weak bond, the cleavage resulting in the initiation of a chain reaction involving the chain reactants.

Abstract: A polymer composition that comprises a polyarylene sulfide, inorganic fibers, impact modifier, and a functionalized coupling system is provided. The functionalized coupling system includes a disulfide compound and an organosilane compound. The weight ratio of organosilane compounds to disulfide compounds is from about 0.1 to about 10.
