Abstract: The invention provides an improved cellulosic ester or ether product with a degree of substitution of between 2.0 and about 2.9 which is derivatized or further reacted by reaction with an acrylamide reactant to substitute to a D.S. of from about 0.05 to about 0.5 and provide a hydroxyl D.S. of from about 0.05 to about 0.5, and thereby provide a polymerizable organic solvent-soluble product which is insoluble in water and copolymerizable with vinyl monomers. The product is prepared by reacting a cellulose derivative with a catalyst and the acrylamide reactant at a pH of from between about 4.2 and about 4.5. The reaction is carried out at a temperature between 80.degree. C. and 120.degree. C. for from one-half to three hours, while removing the water of reaction.

Abstract: Graft copolymers of cellulose derivatives and N,N-diallyl,N-N-dialkyl ammonium chlorides or bromides are prepared using a dry or substantially solvent-free system by impregnating a concentrated aqueous solution of the N,N-diallyl-N,N-dialkyl ammonium halide, water soluble surfactant and catalyst onto the dry cellulose substrate, heating the reaction mass for sufficient time to achieve polymerization and then drying.

Abstract: A modified polyether polyol for use in the manufacture of polyurethane polymer having improved fire-resisting qualities, and the method for making such a polyether polyol. The modified polyether polyol includes a polyether polyol having urea chemically bound thereto. The method for making the modified polyether polyol includes reacting a reducing sugar with propylene oxide to produce a polyether polyol, which is then reacted with unsubstituted urea to chemically bind the urea thereto to produce a modified polyether polyol.

Abstract: Aminopolysaccharides and copolymers thereof, primarily those of N-acetyl-D-glucosamines and derivatives and various monomers, is described.

Abstract: A cellulose derivative-containing emulsion composition which is the product of emulsion polymerization of at least one ethylenically unsaturated monomer in the presence of a water-solubilized product of a cellulose derivative-modified vinyl copolymer having an acid value of from about 3 to about 150, said vinyl copolymer being obtained by copolymerizing a cellulose derivative with an ethylenically unsaturated monomeric component composed of an ethylenically unsaturated acid and another ethylenically unsaturated monomer.

Abstract: Thermoplastic moulding compositions of co-graft polymers which are obtained by the polymerization of vinyl monomers, in particular by the polymerization of unsaturated esters, in the presence of mixtures consisting of the following:1. elastomers having glass transition temperatures .ltoreq.0.degree. C.,2. polyesters, polyethers, polyesterurethanes, polyurethanes, polycarbonates or mixtures thereof, and optionally3. cellulose esters of aliphatic C.sub.1 -C.sub.5 carboxylic acids,and moulding compositions consisting of mixtures of these co-graft polymers with organic cellulose esters.

Abstract: Graft copolymers having starch as the central chain with grafted side chains of acrylamide or acrylamide-acrylic acid, and a process for preparation of such copolymers in the presence of Ce.sup.+4 or other redox initiators. These copolymers are employed in preparing highly viscous aqueous solutions that are particularly useful in oil recovery from subterranean wells.

Abstract: A process is provided for preparing a graft polymermodified cellulose pulp filler from cellulose sulfite pulp having an R.sub.18 value greater than 80%, which comprises adding to the pulp a redox initiator; washing the pulp with water having a pH below 5 in an amount sufficient to adjust the redox initiator cation content to within the range from about 5 to about 1000 ppm of cellulose sulfite pulp; adding hydrogen peroxide in an amount to provide within the range from about 0.1% to about 4% H.sub.2 O.sub.2 by weight of the sulfite pulp; and then reacting the pulp with at least one monomer having the formula: ##STR1## in which: R.sub.1 is hydrogen or methyl; andR.sub.2 is selected from the group consisting of nitrilo --CN, ##STR2## and COOR.sub.3 groups, wherein R.sub.3 is selected from the group consisting of methyl, ethyl, n-butyl, isobutyl and 2-ethylhexyl; at a temperature at which grafting of the monomer onto the cellulose polymer molecule proceeds but below about 70.degree. C.

Abstract: A polyester textile product having durable antistatic and soil release properties, said product being impregnated with the reaction product of; a cellulose ether or ester, a polyamine and a polyepoxide.

Abstract: Acrylic monomers are grafted onto starch-containing materials by a novel dry state process in which small amounts of peroxides chemically initiate the free radical reaction. Since the process is dry and the resultant products contain no contaminants, it is unnecessary to isolate, wash, and dry them before use. The products are useful in the paper and mineral separation industries.
