  • Coating composition comprising an alkoxysilane, a polysiloxane, and a plurality of particles
    Patent number: 8563648
    Abstract: The present invention is directed to a coating composition, such as a substantially clear coating composition, which comprises (1) an alkoxysilane, (2) a polysiloxane, (3) a plurality of particles, and (4) curing agent that is reactive with the polysiloxane. The coating composition of the present invention can exhibit increased physical properties, such as scratch resistance, when compared to similar coating compositions that lack the components disclosed herein.

  • Synthesis of polyanhydrides
    Publication number: 20050131199
    Abstract: The present invention provides a method for forming compounds of Formula HO—C(?O)R1—X—R2—X—R1—C(?O)—O—H wherein compound (I) can be polymerized to provide a polymer that contains therapeutically active compounds. In the compounds of the invention, each R1 is group that will provide the therapeutically active compound upon hydrolysis of the polymer; each X is independently an ester linkage or an amide linkage; and R2 is a linking group.
