  • Patent number: 6992146
    Abstract: A process is provided for the production of a very low melt viscosity (high melt flow index) polymer resin, suitable for use in spunbond or meltblown processing. According to the process of the current invention, a high melt viscosity (low melt flow index) resin is subjected to post-reactor molecular weight alteration by extrusion with a chemical prodegradant. The process produces a very low melt viscosity resin that can be used in spunbond or meltblown processing without further treatment to reduce the average molecular weight of the resin. Further, the very low melt viscosity resins produced according to the process of the current invention contain very little or no residual prodegradant.

  • Patent number: 6733898
    Abstract: Polypropylene resin compositions are provided that are useful in the production of biaxially oriented polypropylene films (BOPPs). The resins of the present invention are blends of high crystalline (low solubles) polypropylene homopolymer and an ethylene/propylene random copolymer (RCP). These blends can be used to replace standard high solubles BOPP grade polypropylene homopolymers. In addition, the use of high crystalline polypropylene homopolymers in the blends imparts improved stiffness to the finished films while maintaining good processability of the blends.

  • Patent number: 6667178
    Abstract: A method for determining the quantity of phenol extracted into an aqueous solution of an alkali metal hydroxide uses a measurement of the pH of the solution, from which the equivalents of phenol relative to alkali metal hydroxide in solution is determined. A method for optimizing the use of an aqueous solution of an alkali metal hydroxide in a phenol recovery process uses pH measured to regulate the feed rate of the aqueous solution.

  • Patent number: 6649716
    Abstract: A process for producing polymers of &agr;-methylstyrene uses tin IV chloride as a polymerization initiator. Use of tin IV chloride as an initiator allows polymerization to proceed without purification of the monomer prior to processing. Polymerization can be carried out at ambient temperatures with mild exotherms and good polymer yields. The process uses solvents commonly found in a plant producing &agr;-methylstyrene.

  • Patent number: 6525232
    Abstract: The invention provides process and apparatus for conducting an endothermic reaction of an organic compound in the presence of molecular hydrogen and of multicomponent solids. The process comprises contacting the compound with a solid catalyst for the endothermic reaction and a hydrogen oxidizing solid reagent intermixed with the solid catalyst. Organic products of the endothermic reaction are produced, with evolution of molecular hydrogen. The solid catalyst becomes gradually deactivated by formation of carbonaceous deposits thereon. The evolved hydrogen undergoes an exothermic reaction with the hydrogen oxidizing solid reagent to form a reduction product which comprises deactivated hydrogen oxidizing solid reagent.
