1501353 Laminates TORAY INDUSTRIES Inc 10 Feb 1976 [10 Feb 1975] 05220/76 Heading B5N [Also in Division C3] Laminates are made using a thermoplastic composition, which contains no halogenated flame-retardant, comprising by wt. 50-99% polyester (A), 50-1% α-olefin copolymer (B), and 0À1-20%, based on (A)+(B), of a compound (E) having 1 or 2 epoxy groups; wherein (A), #50% mol of the dicarboxylic acid component (C) is derived from terephthalic acid, and #50% mol glycol (D) component is derived from butane-1,4-diol. (C) may comprise 5-50 mol per cent isophthalic acid, (B) may be derived from (F) ethylene or propylene and (G) vinyl acetate, (meth)acrylic acid, Zn, Ca, Na, methyl, or glycidyl acrylate, or maleic acid or anhydride. In (B), there may be 0À1-40% wt. (G). Also present may be, by wt. based on (A+B+E), 0À5-30% of polypropylene or a polyester different from (A). Substrates, to which the composition may be applied include, Fe, steel, Al, Cr, Cu, brass, bronze, Ni, Zn, Ti, or Sn; film of polyester, polycaprolactam, or polypropylene; knitted, woven, or non-woven fabric; wood, paper, or leather. This application may be performed by applying the composition as a film or sheet to a preheated surface. In examples, the laminated substrates are: (1), (3), (4), (5) and (7) steel plates; (2), (8), and (11) chrome-coated steel plates; (6) Al plates; (9) polyethylene terephthalate film and (10) fabric woven from a polyethylene terephthalate/ cotton blend. |
