Abstract
A particulate polyolefin molding material is disclosed. The material is comprised of a particulate polyolefin particle having a bulk density of 0.45 g/cc or more and a mean particle size of 150 to 2,000.mu., and a layer comprising a compounding additive and a binder formed on the surface of the particle. The material can be used in producing molded articles without first forming the material into pellets as is conventionally done.
