Aqueous dispersion of an oxazoline group-containing polymer
10730963 · 2020-08-04 · ·

A process for preparing aqueous dispersions of polymers containing oxazoline groups, by aqueous emulsion polymerization initiated by free radicals. The polymerization are carried out in two stages. In the first polymerization stage, an ,-monoethylenically unsaturated compound having at least one acid group, an monoethylenically unsaturated compound having at least one carboxylic acid amide group, a monoethylenically unsaturated compound having at least one carboxylic acid amide group are copolymerized. In the second polymerization stage, a monoethylenically unsaturated compound having at least one oxazoline group, a monoethylenically unsaturated compound having at least one carboxylic acid amide group and an ethylenically unsaturated compound are copolymerized with the final product from the first polymerization stage.

SYSTEMS AND METHODS TO PRODUCE TREATED CELLULOSE FILAMENTS AND THERMOPLASTIC COMPOSITE MATERIALS COMPRISING TREATED CELLULOSE FILAMENTS
20200239650 · 2020-07-30 ·

A method and system to produce treated Cellulose Filaments (CF) and CF products are provided. Feedstock comprising CF in a water solution are mixed with a debonder to produce a mixed stream. The mixed stream is filtered yielding separate filtered and filtrate streams. The filtrate stream comprises at least a portion of the debonder. The filtered stream is dried to produce treated CF. The debonder is one of an alcohol, glycol ether, ester-containing quaternary ammonium salt, amido amine quaternary ammonium salt, disubstituted amide or a mixture thereof. The filtrate stream may be recycled. The mixed stream may be washed before filtering to remove debonder. A thermoplastic polymer-treated Cellulose filament composite material is formable by associating the treated CF with a thermopolymer such as polyolefin, polyurethane (PU), polypropylene (PP), polyester (PE), polylactic acid (PLA), polyhydroxyalkanoates (PHA), polyamide (PA), and ethylene vinyl acetate (EVA) or a mixture.
