Patent number: 8530045Abstract: A process for the production of a polymeric film comprising a copolyester having an acid component and a diol component, said acid component comprising a dicarboxylic acid and a sulfomonomer containing a sulfonate group attached to the aromatic nucleus of an aromatic dicarboxylic acid, said process comprising the steps of: (i) melt-extruding a layer of said copolyester; (ii) stretching the extrudate in at least one direction; (iii) heat-setting the film by raising the temperature of the stretched film to a temperature T1 in a first heating zone such that (TM?T1 is in the range of from 5 to 30° C., and then raising the temperature of the film to a temperature T2 in a second heating zone such that (TM?T2 is in the range of from 0 to 10° C.Type: GrantFiled: February 23, 2010Date of Patent: September 10, 2013Inventors: William Alasdair MacDonald, Pierre Georges Osborne Moussalli, Kenneth Evans, Julian Peter Attard, David Boyce, Brian John Farmer, David Edward Robins

Patent number: 8512519Abstract: Sulfopolyester thermoplastic resins provide advantages in papermaking processes and in paper products including paperboard. Improvements in wet strength and dry strength of paper products are achieved by addition of sulfopolyester thermoplastic resins and cationic strength additives during the paper making process. The use of sulfopolyester thermoplastic resins in paper products also significantly enhances the repulpability of the paper.Type: GrantFiled: April 22, 2010Date of Patent: August 20, 2013Assignee: Eastman Chemical CompanyInventors: Rakesh Kumar Gupta, Daniel William Klosiewicz, Melvin Glenn Mitchell, Marvin Lynn Mitchell
