Title:
PROCESS FOR PRODUCING POLYESTER MOLDING HAVING GOOD GAS BARRIER PROPERTIES
Document Type and Number:
WIPO Patent Application WO/1986/006392
Kind Code:
A1
Abstract:
An anchor coat layer is formed on a polyester molding before coating it with a solution of a vinyl alcohol resin having excellent gas barrier properties, by coating the surface of said molding with a solution in a solvent of a polyester of the following formulation having a limiting viscosity of 0.4 or more: acid component: terephthalic and/or isophthalic acid 90 to 40 mol %; aliphatic dicarboxylic acid containing 2 to 12 carbon atoms 10 to 60 mol %; diol component: straight-chain or cyclic diol containing 2 to 8 carbon atoms 90 to 10 mol %; branched diol containing 3 to carbon atoms 10 to 90 mol %. Thus, a polyester molding with excellent gas barrier properties can be obtained.
