Title: Improved process for the production of extensible contractile tubular, annular or the like film products for example, caps or rings for stoppering bottles
IPC: B29D99/00
Filed: 1947-03-06
Abstract: Extensible contractile film products, e.g. bottle caps, are shaped in an aqueous gel of polyvinyl resin (e.g. vinyl acetate, mixed vinyl acetate and vinyl chloride polymers, vinyl acetates or other water-insoluble polyvinyl resins soluble in organic solvents), and the shaped products are treated with an aqueous solution of a substance which is miscible with water in large proportions, is a swelling agent or gelation agent of the polyvinyl resin and is sufficiently volatile to be completely or largely eliminated during drying.  The treatment of the gel may be carried out as described in Specification 587,309 or during the actual formation of the gel, the solution being used as a coagulation or washing bath.  The gels, which may contain plasticizers and/or fillers, may attain an elasticity when moist of 100-500 per cent, making them suitable for bottle caps.  In examples (1) and (2) the gels are treated with glycol diacetate solution.  In example (3) caps are made from a solution of polyvinyl formal in diethylene glycol and then treated with an aqueous 15-30 per cent by weight solution of glycol diacetate. Specification 644,779 also is referred to.  The Specification as open to inspection under Sect. 91 includes an example in which the shaped products are treated with an aqueous solution of diacetin.
