Patent number: 6060445Abstract: This invention pertains to cleaning compositions and methods for cleaning a first polymer composition from polymer processing apparatus. The cleaning compositions generally comprise a second polymer composition and at least one metal salt composition wherein the respective metal is selected from alkaline earth and transition metals. The second polymer composition has an affinity, for the first polymer, of "Ad" between 50 and about 1500, where "Ad" is adhesive strength, grams/15 mm width, between the first and second polymer compositions in a multiple layer cast coextruded film. The cleaning composition comprises about 0.001 to about 10 weight percent metal salt composition based on total weight of the cleaning composition. A 50/50 weight percent mixture of the second polymer composition, and a third polymer composition which can be processed in polymer processing apparatus suitable for processing the first polymer composition, preferably has a melt index ratio MI-mix.sub.60 /MI-mix.sub.6 of 0.3/1 to 5/1.Type: GrantFiled: March 31, 1997Date of Patent: May 9, 2000Assignee: EVAL Company of AmericaInventors: Vinay Kumar Chandraker, Hidemasa Oda

Patent number: 5965624Abstract: Polymer compositions of the invention typically comprise a base polymer composition, a polymer cleavage agent, and a stabilizer composition. The preferred base polymer composition comprises an ethylene vinyl alcohol copolymer composition. Preferred cleavage agent is an alkaline earth or transition metal salt, preferably an acetate, or a salt of an acid having 8 to 20 carbon atoms. The stabilizer composition comprises an alkylated phenol or bisphenol. Preferred stabilizer composition comprises a tocopherol, preferably alpha tocopherol.Type: GrantFiled: June 27, 1997Date of Patent: October 12, 1999Assignee: EVAL Company of AmericaInventors: Robert Bruce Armstrong, Hidemasa Oda
