  • Vinylidene chloride copolymer latex and film for blister pack
    Patent number: 9884931
    Abstract: Provided is a film for blister packs having barrier capability that is excellent in terms of impact resistance and thermal stability. Also provided is a vinylidene chloride polymer-containing latex that is ideal for producing the film. The coating layer of the film for a blister pack, and the latex, comprise a vinylidene chloride copolymer having a weight-average molecular weight, Mw, between 120,000 and 300,000 that is obtainable by emulsion polymerizing 70 to 95 parts by mass of vinylidene chloride and 30 to 5 parts by mass of one or more other monomer(s) copolymerizable with the vinylidene chloride, with the proviso that the total amount of vinylidene chloride and the other monomer(s) is 100 parts by mass).
    Type: Grant
