Process Of Preparing High Solids Low Viscosity Polysaccharides

View page
US Patent:
54809843, Jan 2, 1996
Filed:
Feb 11, 1992
Appl. No.:
7/834163
Inventors:
John D. Angerer - Hockessin DE
Jashawant J. Modi - Hockessin DE
Robert C. Szafranski - Hopewell VA
Assignee:
Aqualon Company - Wilmington DE
International Classification:
C08B 1120
US Classification:
536 88
Abstract:
Hydroxyethylcellulose (HEC), hydrophobically modified hydroxyethylcellulose (HMHEC), hydroxypropylcellulose (HPC), methylhydroxypropylcellulose (MHPC), carboxymethylhydroxyethylcellulose (CMHEC), guar, starch, xanthan, hydroxypropylguar (HP Guar) or carboxymethylhydroxypropylguar (CMHP Guar) are stepwise or continuously reacted with hydrogen peroxide to produce aqueous compositions with a solids content greater than 5% by weight at a viscosity at 25. degree. C. below 9500 mPa. s. It is preferred to use 30 to 50% hydrogen peroxide to depolymerize the polysaccharide.

Perfluorinated Alkyl Hydrophobe Hydroxyalkylcellulose Associative Thickeners

US Patent:
52908291, Mar 1, 1994
Filed:
Apr 2, 1992
Appl. No.:
7/862416
Inventors:
John D. Angerer - Hockessin DE
Thomas G. Majewicz - Kennett Square PA
Makram H. Meshreki - Wilmington DE
Assignee:
Aqualon Company - Wilmington DE
International Classification:
C08B 1106
C08B 1108
C08B 1114
C08J 305
US Classification:
524 31
Abstract:
A purified hydroxyethylcellulose (HEC) or hydroxypropylcellulose (HPC) reacts with a perfluorinated alkyl glycidyl ether to produce an associative thickener wherein a fluorinated C. sub. 8 chain is nearly as effective as a hydrocarbyl C. sub. 16 straight chain hydrophobe. A preferred glycidyl ether is prepared by reacting a terminal hydroxyl of a perfluorinated surfactant with epichlorohydrin.
