Disclosed are terpolymers having improved barrier properties and tensile strength relative to PET comprising copolyesters derived from acid components comprising about 45 to about 85 mol % terephthalic acid; about 10 to about 40 mol % of at least one naphthalenedicarboxylic acid and about 5 to about 15 mol % of at least one aliphatic dicarboxylic acid having 1 to 6 carbon atoms and glycol component comprising ethylene glycol. The copolyesters of the present invention may be formed into a variety of articles such as blood tubes, serum vials, containers, films and sheeting.

Pet copolyesters containing succinic and naphthalenedicarboxylic acid

Disclosed are reinforced polyester compositions having repeat units from terephthalic acid and 1,4-cyclohexanedimethanol which have improved melt stability due to the addition of small amounts of an epoxy compound and either a phosphite or phosphonite.

Poly(1,4-cyclohexylenedimethylene terephthalate) with improved melt

This invention relates to poly(1,4-cyclohexylenedimethylene terephthalate) (PCT) compositions with improved crystallization characteristics due to the presence of a high molecular weight aliphatic polyester. Specifically, the invention is directed to PCT compositions containing an aliphatic polyester with a number-average molecular weight of at least 8,000.

Reinforced molding composition based on poly(1,4-cyclohexylene

This invention relate to a reinforced molding composition comprising a polyester or copolyester further comprising repeat units derived from terephthalic acid and 1,4-cyclohexanedimethanol having an inherent viscosity of from about 0.5 to 1.0 g/dL and about 1-10% by weight of the total composition of a low molecular weight polyester glutarate.

Reinforced molding compositions with improved crystallization properties

Disclosed is a composition comprising a polyester of terephthalic acid, 1,4-butanediol and/or 1,4-cyclohexanedimethanol, a halogenated organic compound, an antimony compound and a polymer of at least one olefin which contains acid, anhydride or epoxide functional groups. The composition has improved flame resistance. Also disclosed is a method for improving the flame resistance of polymeric compositions.

Polyester molding composition having improved flame resistant

Disclosed is a polyester molding composition comprising poly (1,4-cyclohexylene dimethylene terephthalate), glass fibers and an amide compound as a crystallization aid.

Molding compositions based on poly(1,4-cyclohexylene dimethylene

A glass fiber reinforced composition comprising

Polyesteramide resins useful for forming containers having improved resistance to gas permeability comprising the reaction product of

Polyesteramide from amino alcohol with improved gas barrier properties

A flame-retarded polyester molding composition having improved physical properties comprising

Polyester molding compositions

The present invention provides novel polyesteramides and containers having improved gas barrier properties formed therefrom. The novel polyesteramides comprise the reaction product of a diamine having 2 to about 20 carbon atoms, a diol containing up to about 24 carbon atoms, and a dicarboxylic acid component. The dicarboxylic acid component consists essentially of about 5 to 100 mole % of a specified first, heteroatom-containing dicarboxylic acid, and 0 to about 95 mole % of a second dicarboxylic acid containing up to about 24 carbon atoms. In the polyesteramide, the diamine component comprises about 10 to 90 mole % of the total diamine and diol components. The present invention further provides containers, such as molded containers, films, coextruded articles, laminated articles, etc., formed from the polyesteramides of the present invention.

Polyesteramides and containers having improved gas barrier properties

Disclosed are copolyesters characterized by relatively high glass transition temperatures and low oxygen permeability, the copolyesters being derived from
