Core-shell polymer emulsion with PVDC and acrylic resins as heat-sealable barrier film coatings

摘要

Core-shell two component polymer emulsions in which one component in either the core or the shell is a polyvinylidene chloride polymer and the second component is an acrylic resin containing less than 50 weight percent vinylidene chloride are prepared by polymerizing the monomers of one component in the presence of an emulsion of the other component to give a core-shell product useful for the production of heat-sealable barrier coatings for polymers such as oriented polypropylene.
