Abstract: Blends of hydrocarbon polyolefin, reinforcing fiber, acid copolymer of .alpha.-olefin and .alpha.,.beta.-ethylenically unsaturated carboxylic acid and wetting agent are provided wherein the acid copolymer has from 0 to about 90 percent of the acid groups ionized by neutralization with metal ions. Such blends have excellent Izod impact values and fast molding cycles and as such are particularly suitable as molding resins.

Abstract: Wax-free hot melt adhesive compositions based on a copolymer of an .alpha.-olefin, especially ethylene, with an unsaturated carboxylic acid, especially an .alpha.,.beta.-unsaturated carboxylic acid, or with maleic anhydride and optionally also with another unsaturated carboxylic acid or ester; a tall oil rosin; and a hydrocarbon oil provide good quality bonds. When the level of oil is less than 15%, particularly up to about 13%, there is no oil exudation. The hot melt adhesive compositions of this invention have a good melt viscosity stability when an antioxidant, especially a hindered phenol or organic phosphite, is added. These compositions are useful for heat sealing cartons and for similar applications. Formulations containing tall oil rosins and processing oils approved by the Food and Drug Administration can be readily prepared.

Abstract: An improved process for melt cutting ethylene polymers is provided wherein the improvement comprises adding to the melt cutter water a small amount of nonionic or anionic surfactants thereby significantly increasing the agglomeration temperature of the ethylene polymer. This allows for an increase in melt cutting capacity and productivity.
