Abstract
Halogenated polyethylene resins and halogenated ethylene polymer resins having a reduced tendency to 'block' are provided. The halogenated resins are prepared respectively from polyethylene and ethylene polymer starting materials which have a weight-based median particle size of from about 120 to about 600 microns and a weight-based particle size distribution such that more than 60 percent of the particles have a particle size of from about 130 to about 850 microns. The halogenated resins also have a weight-based median particle size of from about 200 to about 900 microns. The halogenated polyethylene resins have a chemically combined halogen content of from about 26 to about 42 weight percent whereas the halogenated ethylene polymer resins have a chemically combined halogen content of from about 15 to about 28 weight percent. The halogenated ethylene polymer resins are prepared from ethylene polymer starting materials which have polymerized therein up to five weight percent of 1-olefin monomer copolymerizable with ethylene.
