  • Patent number: 8507572
    Abstract: The present invention relates to functionalizing a surface of an organic material. For example, surfaces of materials having C—H bonds, such as polymers having C—H bonds, can be functionalized. In certain embodiments, a heterobifunctional molecule having a photoactive anchor, a spacer, and a terminal functional group is applied to the surface of an organic material that contains one or more C—H bonds. The heterobifunctional molecule can be bound to any surface having C—H bonds as the photoactive anchor can react with C—H bonds upon irradiation. The terminal functional group has a “click” functionality which can be utilized to functionalize the surface of the organic material with any desired functionalizing moiety having the orthogonal click functionality.

  • Patent number: 7226957
    Abstract: A method for producing polymers with controlled molecular weight and desired end functionalities and the resulting polymers. The method comprises a) forming a microemulsion comprising monomer, water, and an effective amount of an effective surfactant, b) adding to the microemulsion an amount of a water-soluble photo-initiator system wherein the initiator system produces one type of monomer-soluble radical active centers and wherein the radical active centers contain desired end group functionalities for a polymer or oligomer, and c) illuminating the microemulsion to photoinitiate polymerization of the monomer wherein the illuminating is according to a temporal and spatial illumination scheme, and wherein the amount of the initiator system and the temporal illumination scheme are chosen to produce a desired molecular weight of the polymer or oligomer. The microemulsion can further comprise an effective amount of an effective co-surfactant. The method can be used to produce polymers and copolymers.
