    摘要: A solvent composition and system is disclosed having a composition including n-propyl bromide and a propionate containing liquid and/or a butyrate containing liquid. The solvent system may include approximately 35 to 92.5 weight percent propionate containing liquid and approximately 7.5 to 65 weight percent n-propyl bromide. Alternatively, the solvent system may include approximately 40 to 85 weight percent butyrate containing liquid and 15 to 60 weight percent, n-propyl bromide. The solvent system may incorporate a polymer, such as a synthetic rubber polymer. Further the solvent system preferably has high solvency while maintaining desirable evaporation rates and is preferably nonflammable, combustible, or minimally a class IC flammable liquid.

    摘要: Silated polysaccharides having 0.005 to 2.0 silyl molar substitution per anhydrosaccharide unit form water resistant films when cast from aqueous solution and dried in the presence of atmospheric cabron dioxide. These films are soluble in aqueous caustic. A preferred water soluble polymer is a cellulose ether with 0.005 to 1.0 silyl substitution.
