Abstract: Polyaminofunctional alkoxy polysiloxanes which exhibit antineoplastic activity are disclosed. Pharmaceutical compositions including an effective amount of a polyaminofunctional alkoxy polysiloxane and/or a pharmaceutically acceptable salt thereof are also disclosed. The application also describes methods of suppressing the growth of neoplastic cells and treating neoplastic conditions.

Abstract: Functionalized cross-linked polysiloxanes, such as quaternary ammonium terminated cross-linked polyalkylsiloxanes are described herein. The functionalized cross-linked polysiloxanes may be used in an antifouling composition to prevent biological fouling in aqueous and/or marine environments.

Abstract: Applicants have produced a chromophore and a polymer that are highly sensitive to the presence of various agents, including organophosphates, pesticides, neurotoxins, metal ions, some explosives, and biological toxins. The detection is accomplished by detecting a change in the fluorescence characteristics of the chromophore or polymer when in the presence of the agent to be detected. The chromophore and polymer may be incorporated into sensors of various types, and they are adaptable for potential field use in areas where detection of these types of agents is desired.

Abstract: Polyamine cross-linked polysiloxanes, such as functionalized polysiloxane cross-linked with a polyalkylenepolyamine are described herein. The polyamine cross-linked polysiloxanes may be used in an antifouling composition to prevent biological fouling in marine environments.

Abstract: An anti-fouling material useful to prevent fouling of structure exposed to a water environment includes a copolymer having a carbon and/or silicone backbone with a pendant biocidal group and, optionally, a pendant fouling release group.

Abstract: A method for the redistribution of trichlorosilane in the presence of N,N,N',N'-tetraethylethylenediamine (TEEDA) to form a complex comprising dichlorosilane and TEEDA. The dichlorosilane can be disassociated from the TEEDA by a means such as heating and then used in standard processes requiring dichlorosilane. Alternatively, the complex comprising the dichlorosilane and TEEDA can be used as a reactant for hydrosilation of .alpha.,.beta.-unsaturated olefinic nitriles or reacted with Grignard type reagents to make organosilanes.
