Cationic and silicon substituents are introduced into polysaccharides thereby producing modified polysaccharides cationically substituted by quaternary ammonium groups and having a charge density of about 0.1 to about 2.5 meq/g, and further substituted by siliconate groups such that the modified polysaccharide has a silicon content of about 300 to about 5000 ppm. The modified polysaccharides have application in industrial, home care and personal care surface modifying formulations.

Described herein are methods for chemical modification of nitrocellulose to generate lyophobic properties which are useful in propellant compositions. Such methods include the steps of: a) dissolving neat nitrocellulose in an organic solvent; b) adding a silyl based isocyanate and a catalyst to the solution; (d) stirring the solution in a moisture free environment; e) hydrolyzing the solution by exposing said solution to moisture; and (e) adding fluorinated oxysilane. The modified nitrocellulose retains its energetic properties while exhibiting high water and organic solvent phobicity, effectively functioning as a barrier to migration or diffusion of liquid components in propellant compositions.

Described herein are hemi-aminal ethers and thioethers of N-alkenyl cyclic compounds that may be produced through a reaction comprising: (A) at least one first reactant represented by a structure (I), wherein X is a functionalized or unfunctionalized C.sub.1-C.sub.5 alkylene group optionally having one or more heteroatoms, and each R.sub.1, R.sub.2, and R.sub.3 is independently selected from the group consisting of hydrogen and functionalized and unfunctionalized alkyl groups optionally having one or more heteroatoms, and (B) at least one second reactant having at least one hydroxyl moiety or thiol moiety. The hemi-aminal ethers and thioethers of N-alkenyl cyclic compounds may comprise a polymerizable moiety, in which case they may be left as-is or used to create homopolymers or non-homopolymers, or they may not comprise a polymerizable moiety. A wide variety of formulations may be created using the hemi-aminal ethers and thioethers of N-alkenyl cyclic compounds, including personal care, oilfield, and construction formulations. ##STR00001##
