Abstract:
1. A composition, comprising: a polymer blend comprising at least one polyester matrix resin, and at least one co-barrier resin; wherein the polyester resin has an intrinsic viscosity of from 0.7 to 0.9 at 30° C. in a mixed solvent of 60% phenol and 40% 1,1,2,2-tetrachloroethane, wherein % is wt % based on the total weight of phenol and 1,1,2,2-tetrachloroethane and is obtained by melt polymerizing a mixture comprising one or more dicarboxylic acids and one or more diols; and wherein the co-barrier resin is one or more of a polyamide resin, a co-polyamide resin, a co-polyamide ionomer, an amide-functionalized polyester resin, and a resin having non-linear attachment to one or more of a benzene and a naphthalene ring present therein, comprising reacted units of adipic acid, isophthalic acid, and meta-xylene diamine.
