Migration-Resistant Binder Compositions For Bonding Nonwoven Fibers; Also Methods And Articles

View page
US Patent:
41994000, Apr 22, 1980
Filed:
Jun 13, 1977
Appl. No.:
5/806047
Inventors:
Ronald D. Bakule - Jenkintown PA
R. A. Gill - Abington PA
Lawrence K. Wempe - Lansdale PA
Assignee:
Rohm and Haas Company - Philadelphia PA
International Classification:
D04H 164
D21F 1100
D21H 512
D21H 514
US Classification:
162146
Abstract:
Migration-resistant binder compositions for bonding nonwoven fibers are disclosed. These compositions comprise (A) an anionically-stabilized polymer latex; (B) a water-soluble polymer of 20-100% by weight of mer units containing an amine group and having a viscosity average molecular weight between 5,000 and 300,000; (C) a volatile base and (D) 0 to 80% of pigment based on the total polymer weight of (A) and (B). Usually, the compositions have a solids content between 10% and 60% by weight, a viscosity below 3,000 centipoise, a pH above 5, and a component (B) content between 0. 1% and 20% by weight of the solids. In alternative compositions, component (B) is replaced by component (B'), a water-insoluble polymer with the same amine group content and a viscosity average molecular weight between 5,000 and 100,000. (A), (B) and (B') are polymers of a. alpha. -. beta. ethylenically unsaturated monomers.

Release Coatings Based On Polyvinyl Alcohol

View page
US Patent:
43861830, May 31, 1983
Filed:
Apr 16, 1981
Appl. No.:
6/254833
Inventors:
Lawrence K. Wempe - Center Valley PA
Assignee:
Air Products and Chemicals, Inc. - Allentown PA
International Classification:
C08K 338
US Classification:
524405
Abstract:
Polyvinyl alcohol based release coating compositions for strippable substrates which are in contact with pressure sensitive adhesives are disclosed. Substrates coated with the release compositions are easily peeled from pressure sensitive adhesive coated substrates without substantially adversely affecting the adhesive character of the adhesive coated substrate. The release coating composition comprises polyvinyl alcohol, a migratable release promoting agent, a water soluble salt of a coordinating metal and a water soluble boron compound in an aqueous solution. In addition to composites comprising release coated substrates affixed to adhesive coated substrates, the release compositions can be applied to the backing of a pressure sensitive adhesive tape to permit facile uncoiling of the rolled tape product.

Vinyl Acetate/Ethylene Copolymer Emulsions For Paper Coating Compositions

View page
US Patent:
45031851, Mar 5, 1985
Filed:
Jun 22, 1984
Appl. No.:
6/623676
Inventors:
Mary L. Hausman - Barto PA
Gerald D. Miller - Macungie PA
Lawrence K. Wempe - Center Valley PA
Assignee:
Air Products and Chemicals, Inc. - Allentown PA
International Classification:
C08L 5504
US Classification:
524553
Abstract:
Aqueous vinyl ester/ethylene copolymer emulsions possessing good dry pick and wet pick strengths in paper coating compositions comprise a vinyl ester/ethylene copolymer colloidally dispersed in an aqueous medium, the copolymer consisting essentially of (a) a vinyl ester of a C. sub. 1 -C. sub. 12 alkanoic acid, (b) about 0. 5 to 15 wt % ethylene, (c) about 0. 1 to 10 wt % of an ethylenically unsaturated mono- or dicarboxylic acid or half ester thereof, (d) about 0. 05 to 10 wt % of a dicyclopentadienyl acrylate, and (e) 0-50 wt % of an alkyl acrylate.

Method For Reducing Wall Fouling In Vinyl Chloride Polymerization

View page
US Patent:
44205910, Dec 13, 1983
Filed:
Apr 5, 1982
Appl. No.:
6/365117
Inventors:
Lawrence K. Wempe - Center Valley PA
Bernard D. Bauman - Coopersburg PA
Assignee:
Air Products and Chemicals, Inc. - Allentown PA
International Classification:
C08F 1406
US Classification:
526 62
Abstract:
This invention relates to an improvement for reducing the amount of wall fouling in the suspension polymerization of vinyl chloride. The improvement resides in wetting the reactor surface with a solution containing selenous acid prior to charging the vinyl chloride recipe to the reactor. Preferably, the surface of the resulting reactor is heated at a temperature of from 40. degree. -100. degree. C. prior to charging the recipe.

Vinyl Alcohol Copolymers Containing Allylamine Functionality

View page
US Patent:
51551675, Oct 13, 1992
Filed:
Oct 30, 1989
Appl. No.:
7/428805
Inventors:
Robert K. Pinschmidt - Allentown PA
Lawrence K. Wempe - Center Valley PA
Assignee:
Air Products and Chemicals, Inc. - Allentown PA
International Classification:
C08F 812
US Classification:
525 60
Abstract:
A modified poly(vinyl alcohol) copolymer is provided containing copolymerized units of allylamine and/or diallylamine by copolymerizing a vinyl ester, such as vinyl acetate, and an N-allylamide and/or N,N-diallylamide, such as N-allylformamide and/or N,N-diallylformamide and hydrolyzing first the ester groups to hydroxy groups and then the amide groups to amine groups. The second hydrolysis is carried out on solvent-swollen particulate polymer slurried in an acidic or basic medium. The modified polymer can contain small amounts of unhydrolyzed ester and amide groups in addition to the hydroxy and amine functionality which characterizes the copolymer.
