  • Enhancement of ethylene-vinyl acetate adhesion to polyester sheet by post-reaction
    Patent number: 4530878
    Abstract: The inter-layer adhesion of laminates comprised of alternating layers of thermoplastic polyester and ethylene-vinyl acetate copolymer is greatly enhanced by a method of treatment of the laminate with a stream of inert gas at elevated temperatures which is described. The treated articles in general exhibit a T-peel strength of 1 in. lb./in..sup.2 and greater, which is far in excess of the peel strengths typical of the untreated article.

  • Copolyetherimides and process of preparation
    Patent number: 4504650
    Abstract: Copolyetherimides having random units in the structure and characterized by good transparency after molding are prepared by a process in which a dianhydride and a diamine are reacted at a temperature of at least 100.degree. C. to initiate polymerization, followed by the addition of a second anhydride and continuing the polymerization at the elevated temperature. Preferred features include conducting the reaction in a solvent and in the presence of a chain stopper, such as phthalic anhydride.
