  • Patent number: 9527964
    Abstract: The present invention is generally directed to a new class of TPEs made from peptide terminated low Tg polymers and methods for making them. The middle block of these TPE is a telechelic polymer with a Tg that is below the intended service temperature of the TPE. The terminal peptide segments of these TPEs are short (from about 1 to about 10 amino acids long) and tend to from sheet type secondary structures through intermolecular hydrogen bonds, creating physical crosslinks between polymer chains. The dissimilarity of the peptide hard component and the elastomeric soft component results in very strong segregation between the microphase domains and a low plastic deformation for the resulting TPE. And since the Tm of the crystalline peptide phase can be adjusted, these new TPEs may be tailored to fit the intended service temperature and are melt-processable.

    Abstract: A method is presented for making alkoxy-modified silsesquioxanes (AMS) or co-alkoxy-modified silsesquioxanes (co-AMS,) comprising the steps of (a) combining as a reaction mixture (i) water, (ii) an acid-stable solvent for the water, (iii) a solid strong cationic hydrolysis and condensation catalyst, and (iv) a trialkoxysilane compound, (b) allowing the reaction mixture to react for about 0.5 hours to about 200 hours to form the alkoxy-modified silsesquioxanes; and (c) recovering the alkoxy-modified silsesquioxanes from the reaction mixture. The use of solid strong cationic catalysts in this reaction system is advantageous because they remain as solids throughout the reaction, allowing simplified separation of the solid catalyst from the soluble AMS or co-AMS products, resulting in total or near total recovery of the AMS or co-AMS products, the products being free of, or substantially free of residual acid catalyst, as well as virtual total recovery of the catalyst for recycling.

  • Patent number: 7514518
    Abstract: The present invention relates to a process for preparing organopolysiloxanes by reacting halosilane with alcohol and water in the presence of the desired organopolysiloxane in a reaction unit comprising a distillation column, optionally a reflux condenser, and a vessel already containing desired organopolysiloxane, by heating the vessel contents to boiling under reflux, introducing halosilane into the column above the lower column end, removing hydrogen halide from the distillation column and continuously removing organopolysiloxane from the vessel at the same rate in which it is formed, by constantly adding halosilane, alcohol and water to the reaction unit in such amounts that more water is always present in the reaction unit than is consumed by the added Si-halogen units of the halosilanes.

  • Publication number: 20080248126
    Abstract: Methods for efficient preparation of drug-polymer (or oligomer) conjugates which are useful in the preparation of particles, including microparticles and nanoparticles, for delivery of the drug in vivo for therapeutic applications. The invention additionally provides certain drug-polymer and drug-oligomer conjugates which are useful in the preparation of particles for delivery of the drug in vivo. The invention also provides nanoparticles of this invention prepared by nanoprecipitation using drug-polymer/oligomer conjugates of the invention. The drug conjugates are formed during polymerization of the polymer or oligomer in which the drug is employed as an initiator of the polymerization of the monomers which form the polymer and/or oligomer. More specifically, the drug conjugates are formed by ring-opening polymerization of cyclic monomers in the presence of an appropriate ring-opening polymerization catalyst and the initiator (the drug).

  • Publication number: 20080097065
    Abstract: The present invention includes a composition for a silicon-containing material used as an etch mask for underlying layers. More specifically, the silicon-containing material may be used as an etch mask for a patterned imprinted layer comprising protrusions and recessions. To that end, in one embodiment of the present invention, the composition includes a hydroxyl-functional silicone component, a cross-linking component, a catalyst component, and a solvent. This composition allows the silicon-containing material to selectively etch the protrusions and the segments of the patterned imprinting layer in superimposition therewith, while minimizing the etching of the segments in superposition with the recessions, and therefore allowing an in-situ hardened mask to be created by the silicon-containing material, with the hardened mask and the patterned imprinting layer forming a substantially planarized profile.
