Vinylidene chloride polymer aqueous latex compositions.

摘要

Aqueous latex contact-adhesive compositions comprising at least one vinylidene chloride copolymer comprising polymerised units of vinylidene chloride and at least one internally plasticising comonomer which may be provided at least in part by at least one alkyl (meth)acrylate having 1 to 12 carbon atoms in the alkyl group (preferably n-butyl acrylate), said copolymer having a modal molecular weight Mp within the range 100,000 to 700,000 and Tg within the range -50 to 10°C, said composition providing contactable layers after drying. The composition preferably includes a tackifying resin.
