Abstract
A compatibilized blend of at least three polymers is provided. One polymer is a vinylidene chloride interpolymer, such as a copolymer of vinylidene chloride and vinyl chloride. A second polymer is an olefin polymer, such as polyethylene. A third polymer is a compatibilizing polymer such as an ethylene/alkyl acrylate or an ethylene/alkyl methacrylate copolymer. The compatibilized blend, after melt processing, has mechanical properties which are better than those predicted by a straight line volume fraction relationship of the vinylidene chloride interpolymer and the olefin polymer.
