A roof structure comprises a roof membrane and a roof substrate. A first surface of the roof membrane is adhered to the roof substrate by a two component adhesive, the adhesive being capable of adhering the first surface of the roof membrane to the roof substrate without the use of a high VOC solvent. The two component adhesive includes a Michael donor and a Michael acceptor, and the Michael donor and the Michael acceptor react to form an adhesive film.

Disclosed are amorphous copolyesters having an inherent viscosity (IV) of about 0.5 to 1.1 dL/g measured at a temperature of 25&#xb0; C. at 0.5 g/dL concentration in a solvent mixture of symmetric tetrachloroethane and phenol having a weight ratio of symmetric tetrachloroethane to phenol of 2:3 comprising (1) a diacid component comprising about 90 to 100 mole percent terephthalic acid residues and 0 to about 10 mole percent isophthalic acid residues; and (2) a diol component comprising about 10 to 70 mole percent 1,4-cyclohexanedimethanol residues and about 90 to 30 mole percent neopentyl glycol residues; wherein the amorphous copolyesters comprises 100 mole percent diacid component and 100 mole percent diol component. The amorphous copolyesters are useful in the manufacture or fabrication of medical devices which have improved resistance to degradation upon exposure to lipids, as a profile produced by profile extrusion and as an injection molded article. Also, a method of melt processing the amorphous copolyester is disclosed which allows for performing a minimal drying or no drying of the copolyester prior to melt processing.

The present invention relates to miscible blends of the polycarbonate of bisphenol A and polyesters from aromatic dicarboxylic acids, 1,4-cyclohexanedimethanol, ethylene glycol, and 2,2'-(sulfonylbis(4,1-phenyleneoxy)-bis(ethanol).

Blends of polycarbonate and sulfone copolyesters

Disclosed are amorphous copolyesters having an inherent viscosity (IV) of at least about 0.5 dL/g measured at a temperature of 25&#xb0; C. at 0.5 g/dL concentration in a solvent mixture of symmetric tetrachloroethane and phenol having a weight ratio of symmetric tetrachloroethane to phenol of 2:3 comprising (1) a diacid component comprising about 90 to 100 mole percent terephthalic acid residues and 0 to about 10 mole percent isophthalic acid residues; and (2) a diol component comprising about 10 to 70 mole percent 1,4-cyclohexanedimethanol residues and about 90 to 30 mole percent neopentyl glycol residues; wherein the amorphous copolyesters comprises 100 mole percent diacid component and 100 mole percent diol component. The amorphous copolyesters are useful in the manufacture or fabrication of medical devices which have improved resistance to degradation upon exposure to lipids, as a profile produced by profile extrusion and as an injection molded article.

This invention relates to a process for producing a polyester comprising the steps of:

Method for making isosorbide containing polyesters

Polymer composite materials comprising of least one polymer resin and platelet particles from at least one layered silicate material uniformly dispersed in the resin and articles prepared from the polymer composite materials. The polymer composite contains at least one polyamide resin, at least one oxygen scavenging system, and at least one layered silicate material. These polymer composite materials are especially useful for manufacturing clear polyester bottles and polyester film that are recyclable have improved active gas barrier properties to oxygen, and have improved passive barrier properties to carbon dioxide and other gases. The polymer composite materials can be used in relatively minor amounts as either a blend or a coextruded thin layer with virgin or post consumer recycled polyesters and related copolymners.
