Abstract: A process is described for producing fermentable sugars derivable from biomass that contains polysaccharide, such as cellulose, made increasingly accessible as a substrate for enzymatic degradation or other methods of depolymerization. These fermentable sugars are subsequently able to be fermented to produce various target chemicals, such as alcohols, aldehydes, ketones or acids.

Abstract: In this invention, a process for producing fermentable sugars derivable from biomass that contains polysaccharide, such as cellulose, which has been made increasingly accessible as a substrate for enzymatic degradation or other methods of depolymerization. The process of the present invention increases accessibility of polysaccharides, typically present in biomass and produces polysaccharides with increased accessibility. The polysaccharides with increased accessibility may be subsequently saccharified to yield fermentable sugars. These fermentable sugars are subsequently able to be fermented to produce various target chemicals, such as alcohols, aldehydes, ketones or acids.

Abstract: A water-soluble, associative carboxymethylcellulose (CMC) exhibits unique and highly desirable rheology and performance properties in a wide variety end-use systems. This unique CMC is prepared in a novel staging process. The end-use systems include personal care, household care, paint, building material and construction, pharmaceutical, medical care, oilfield, mineral processing, paper making and paper coating, and food.

Abstract: A curable composition containing (A) a polyene having at least two hydrosilation reactive carbon-carbon double bonds; (B) a cyclic silicon compound, having at least two hydrosilation reactive .tbd.SiH groups; and (C) a linear silicon compound containing at least two .tbd.SiH groups, and having the general formula: ##STR1## wherein R comprises at least one member selected from a group consisting of hydrogen, a substituted or unsubstituted saturated alkyl radical, and a substituted or unsubstituted phenyl radical, and R' comprises at least one member selected from a group consisting of hydrogen, a substituted or unsubstituted saturated alkyl radical, and a substituted or unsubstituted phenyl radical; m is an integer from about 25 to 1000, at least one R' is hydrogen; and the linear silicon compound is present in an amount of from about 5 to 95 weight percent, based on a total weight of silicon compounds present in the curable composition. The curable composition can contain a prepolymer.

Abstract: Disclosed are novel, cross-linked or cross-linkable linear poly(organohydrosiloxanes) wherein the cross-linking units are derived from polycyclic polyenes. These polymers or prepolymers are prepared by reacting or partially reacting the poly(organohydrosiloxanes) with the polycyclic polyene in the presence of a catalyst.
