Process For Transesterification Of Olefin/Acrylic-Ester Copolymers
Process For Transesterification Of Olefin/Acrylic-Ester Copolymers
US Patent:
5656692, Aug 12, 1997
Filed:
Sep 4, 1996
Appl. No.:
8/707686
Inventors:
Richard Allen Hayes - Wilmington DE
Assignee:
E. I. Du Pont de Nemours and Company - Wilmington DE
International Classification:
C08G 6391
US Classification:
525 63
Abstract:
Copolymers comprising olefin and alkyl-acrylate-ester repeat units are transesterified by olefin-containing alcohols in the presence of an alkali metal alkoxide catalyst. The transesterified polymers are especially useful as curable elastomers.
Poly(Vinyl Alcohol) Polymer Blend Textile Sizes With Improved Ability To Be Desized
Poly(Vinyl Alcohol) Polymer Blend Textile Sizes With Improved Ability To Be Desized
US Patent:
5482747, Jan 9, 1996
Filed:

International Classification:
B05D 302, B05D 304, B05D 310
US Classification:
427341
Abstract:
Compositions based on blends of certain specified poly(vinyl alcohol) copolymers and other poly(vinyl alcohol) polymers are described which are useful as sizes, and have improved ability to be desized from fabrics compared with the other poly(vinyl alcohol) polymers alone. The specific poly(vinyl alcohol) copolymers useful in the blends with other poly(vinyl alcohol) polymers are copolymers having a high level of acrylic ester comonomer. The blend sizes are useful in producing woven materials since they are excellent sizes, and are uniquely adaptable to caustic desizing.
