TITLE IMPROVED MINERAL REINFORCED NYLON COMPOSITIONS FOR BLOWMOLDING ABSTRACT OF THE DISCLOSURE It has now been found that a unique combination of additives makes mineral-reinforced semi-crystalline polyamides readily processible by extrusion blowmolding to make hollow, stiff parts of various shapes. The compositions consist essentially of semicrystalline polyamide, 15-50 weight percent mineral filler reinforcing agent, 1-25 weight percent of an ionic copolymer of at least one alpha-olefin and at least one alpha,beta-unsaturated carboxylic acid in which the acid moiety is partially neutralized with metal ions, and 0.1 to 3 weight percent of fibrillar fluoropolymer resin. Percents are by weight of compositions. AD-5599A
