  • Publication number: 20070155926
    Abstract: Polymers comprising a polymer backbone comprising one or more degradable units are described. The polymer may additionally comprise two or more polymer segments comprising radically (co)polymerizable vinyl monomer units. The degradable units may be independently selected from, but not limited to, at least one of hydrodegradable, photodegradable and biodegradable units between the polymer segments and dispersed along the polymer backbone. The degradable units may be derived from one or more monomers comprising a heterocyclic ring that is capable of undergoing radical ring opening polymerization, a coupling agent, or from a polymerization initiator, radically polymerizable monomers, as well as other reactive sources. Embodiments of the degradable polymer of claim are capable of degrading by at least one of a hydrodegradation, photodegradation or biodegradation mechanisms to form at least one of telechelic oligomer and telechelic polymeric fragments of the polymer.

  • Publication number: 20060237695
    Abstract: Polythiophene copolymers having tunable work functions and oxidation voltage onset. The ratio of monomer can be varied to achieve the desired property for a particular application. One monomer can be unsubstituted thiophene. The copolymer microstructure can be random. Another monomer can be a 3-substituted thiophene such as 3-alkyl or a heteroatom substituted substituent. Heterojunction polymer photovoltaic cells can be fabricated with excellent voltage onset properties compared to devices having corresponding homopolymers.

  • Publication number: 20040158013
    Abstract: A method of synthesizing a CO2-philic analog of a CO2-phobic compound, includes the step of: reacting the CO2-phobic compound with a CO2-philic compound selected from the group of a polyether substituted with at least one side group including preferably a Lewis base, a polycarbonate, a polycarbonate substituted with at least one side group including preferably a Lewis base, a vinyl polymer substituted with at least one side group including preferably a Lewis base a poly(ether-ester) or a poly(ether-ester) substituted with at least one side group including preferably a Lewis base, to create the CO2-philic analog. A method of synthesizing a CO2-phile includes the step of copolymerizing at least two monomers, wherein a polymer formed from homopolymerization of one of the monomers has a Tg of less than approximately 250 K and a steric factor less than approximately 1.
