Title:COMPOSITION OF POLYMERIC ROTATIONAL MOLDING POWDER AND METHOD OF USING

Inventor(s):J. White and T. Nagy

Disclosure 165-DIV U.S. Patent not yet issued

A composition for rotational molding of polymeric articles is made by blending reprocessed polymer particles with virgin polymer particles.The composition has from about l to about 80 parts by weight of reprocessed particles and from about 99 to about 20 parts by weight of virgin particles.The particles to be blended are sized so that the larger particles are predominantly virgin particles.The weight fraction of virgin particles in the largest 20% of particles by size is at least 0.80 and preferably 0.95. The weight fraction of virgin particles in the largest 50% of particles by size is at least 0.70 and preferably at least 0.80.
