    摘要： The invention relates to special amyloses for producing biodegradable, clear, transparent and flexible plastic, in particular sheets and films, whicha) are swellable, but not soluble, in cold water;b) yield homogenous, flowable quasi-solutions without formation of gels if they are heated, with stirring, to temperatures above 80.degree. C., at atmospheric pressure; during cooling to a temperature of 50.degree. C., this state is maintained for at least five minutes, without gel formation or retrogradation, and the solution in a concentration between 5 and 25% is applicable to knife coating onto a plane surface with a gap width between 100 and 700 .mu.m.

    摘要： Capsule shells for pharmaceutical use are presently made from gelatin. Use of water-soluble starch ethers instead of gelatin facilitates the production of the shells and produces improved shells. Preferred material is 2-hydroxypropyl starch made from high-amylose starch and having about 0.3 to 2.5 hydroxypropyl groups per glucose unit of the starch.

    摘要： A dip-formed article which is shaped from a dip-formable composition comprising 100 weight parts of a conjugated diene copolymer prepared by copolymerization of 50 to 85 weight % of a conjugated diene monomer with 15 to 40 weight % of an ethylenically unsaturated nitrile monomer, 1 to 4 weight % of an ethylenically unsaturated acid monomer and 0 to 30 weight % of a copolymerizable other ethylenically unsaturated monomer, 2 to 6 weight parts of sulfur and 0 to 0.2 weight parts of zinc oxide. The dip-formed article is characterized as a glove by being well elongated and ease in donning, being not easily broken upon donning, and not wearying a wearer's hand even when it is worn for a long time, and having improved lastingness of the tight conformity to the skin of a wearer's hand.

    摘要： Compositions are disclosed for dewatering mixtures of petroleum and water. The compositions comprise one or more of the following: an unreacted polysaccharide component; and one or both of a polysaccharide component reacted with a hydrophilic component and a polysaccharide component reacted with a hydrophobic component. The compositions may also include viscosifying agents or stabilizers to stabilize the compositions against separation, for example, prior to use. In particularly preferred embodiments the invention is drawn to compositions for breaking an emulsion; such compositions comprising a carbohydrate component containing a cationic starch joined to a hydrophobic moiety, providing the carbohydrate component oil solubility. The composition may optionally comprise one or more additional demulsifier selected from, without limitation, salts (such as a polyaluminum chloride, an aluminum chlorohydrate, an alum, etc.), metal salts (such as iron and zinc salts), dithiocarbamate, tannin, and organic demulsifiers such as poly-DADMAC and similar compounds.
