Patent number: 8247051Abstract: A coating composition is provided for use in laminate substrates useful in packaging of liquids and solids where the coating provides and increased resistance to the permeability of gases such as oxygen and carbon dioxide. In one embodiment the coating composition is a dispersion or a solution that comprises at least one hydroxyl functional polyetheramine, phosphoric acid and a defoamer. The backbone of the polyetheramine has diglycidyl ether linkages that comprise about 5 to about 70 mole percent resorcinol diglycidyl ether. The coating composition can be applied to substrates by coating applications such as spraying, rolling reverse and direct, rolling direct and reverse gravure, kiss coat, flow coating, brushing, dipping and curtain-wall coating, for example.Type: GrantFiled: August 1, 2006Date of Patent: August 21, 2012Assignee: The Glidden CompanyInventors: Daniel Bode, Cathy Li, Kenneth J.

Patent number: 8124717Abstract: A poly(2,6-dimethyl-1,4-phenylene ether) prepared using a morpholine-containing polymerization catalyst has a monomodal molecular weight distribution with a reduced content of very high molecular weight species. It also exhibits increased morpholine incorporation in the high molecular weight fraction. Compared to commercially available poly(2,6-dimethyl-1,4-phenylene ether) prepared using a di-n-butylamine-containing polymerization catalyst, the poly(2,6-dimethyl-1,4-phenylene ether) of the invention exhibits reduced odor. Compared to other poly(2,6-dimethyl-1,4-phenylene ether) prepared using a morpholine-containing polymerization catalyst, the poly(2,6-dimethyl-1,4-phenylene ether) of the invention exhibits improved molecular weight build during compounding and improved compatibilization with polyamides.Type: GrantFiled: April 11, 2011Date of Patent: February 28, 2012Assignee: Sabic Innovative Plastics IP B.V.Inventors: Alvaro Carrillo, Stephen M.
