Patent number: 7420025Abstract: Acyclic diene metathesis (ADMET) has been utilized in the synthesis of carbosilane and carbosiloxane polymers bearing a latent reactive methoxy-functional group on each repeat unit. The polymerization results in a linear thermoplastic polymer. The latent reactive methoxy groups remain inert during polymerization; however, exposure to moisture triggers hydrolysis and the formation of a chemically cross-linked thermoset. The thermoset's properties can be modified by varying the ratio of carbosilane and carbosiloxane repeat units in the final material. Also, increasing cross-link density by using cross-linkable chain-end groups and increasing the run length of the soft phase, maximizing phase separation and elasticity, allows for the synthesis of elastic thermosets exhibiting good tensile strength. Adding a trifunctional ADMET active chain-end cross-linker to the system improved the mechanical behavior of the resulting polymer.Type: GrantFiled: November 21, 2003Date of Patent: September 2, 2008Assignee: University of Florida Research Foundation, Inc.Inventors: Kenneth B.

Patent number: 7056989Abstract: Highly regular and well-defined structured polyorganosilsesquioxane polymer with superior heat resistance, combustion resistance and flexibility, wherein same or different kinds of substituents are bonded alternately, and the preparation method thereof. The polyorganosilsesquioxane prepared according to the present invention has a small molecular weight distribution and a high molecular weight, and is soluble in organic solvents because a three-dimensional network structure is not formed during the preparative condensation polymerization. Polyalkylaromaticsilsesquioxane obtained from the preparing method of the present invention is a useful heat-resistant material. It can be used as a heat-resistant coating agent, a protective coating agent of optical fiber, a coating material for resistor, heat-resistant paint, an adhesive and a releasing agent for precise molding. Also, it can be used for the semiconductor protective layer, interlayer dielectrics for semiconductor integration (e.g.Type: GrantFiled: March 13, 2003Date of Patent: June 6, 2006Assignee: Korea Institute of Science and TechnologyInventors: Seung Sang Hwang, Soon Man Hong, Eung Chan Lee, Seung Pyo Hong

Patent number: 7037592Abstract: A fiber reinforced composite including layers of fibers, each layer being impregnated with a resin. The layers include in combination a layer of an addition cured silicone resin and a layer of an organic resin. The layers form a hybrid composite having a higher modulus retention at elevated temperatures than the addition cured silicone resin alone. The hybrid composite's mechanical properties are similar to the organic resin composite, but demonstrate enhanced thermal resistance and reduced flammability.Type: GrantFiled: February 25, 2003Date of Patent: May 2, 2006Assignee: Dow Coming CorporationInventors: Bizhong Zhu, Herschel H. Reese, Dimitris E. Katsoulis, John R. Keryk, Yuhong Wu, Frederick J. McGarry

Patent number: 6995215Abstract: Hyperbranched polymers having a plurality of at least two different types of functional groups are described. Specific embodiments include hyperbranched polymers having functional groups of a first type that are substantially uniformly distributed throughout the hyperbranched polymer molecule and a second type of functional group that is substantially uniformly distributed at the terminals of the hyperbranched polymer molecule. The hyperbranched polymers having different types of functional groups are synthesized by reacting one or more monomers having functional groups that are capable of reacting during a set of polymerization conditions to form a hyperbranched polymer, wherein at least one of the monomers contains latent functional groups that are not reactive during polymerization.Type: GrantFiled: June 2, 2003Date of Patent: February 7, 2006Assignee: Michigan Molecular InstituteInventors: Petar R.
