In yet other instances the substituted phenacyl molecules extend as a side chain from the polymer/copolymer backbone, and a drug or polymer additive is linked to the photoresponsive substituted phenacyl group such that photoirradiation releases the drug or additive. In yet other embodiments the substituted phenacyl molecules extend as a side chain from the polymer/copolymer backbone, and serve to link the polymer/copolymer to another polymer/copolymer backbone, and photoirradiation breaks the links.

  • Publication number: 20140242623
    Abstract: We disclose methods and compositions for preparation of stimuli-responsive plastics that are capable of responding to chemical and/or physical signals in their environment. In one embodiment the plastics consist of patterned mixtures of poly(phthalaldehyde) polymers in which each polymer contains a different end-capping group (also called a “trigger”), responsive to a different signal. Other embodiments use different polymers and different triggers. The plastics may be homogeneous in composition, but each polymer within the plastic is capable of responding to a different signal and depolymerizing once this signal reacts with the trigger. This process of depolymerization enables the plastic to alter its physical features non-linearly to external signals: i.e., the degree of change in physical form is much larger than the intensity of the initial signal.

  • Patent number: 8389639
    Abstract: A proton exchange membrane comprising modified hyper-branched polymer is disclosed. The proton exchange membrane includes 85-90 wt % of sulfonated tetrafluorethylene copolymer and 15-10 wt % of modified hyper-branched polymer. The modified hyper-branched polymer comprises the bismaleimide (BMI)-based hyper-branched polymer, and parts of the chain ends of the hyper-branched polymer are sulfonated by the sulfonic compound. Also, the modified hyper-branched polymer and sulfonated tetrafluorethylene copolymer are interpenetrated to form an interpenetrating polymer. Furthermore, the modification step could be performed before or after forming the interpenetrating polymer. For example, the sulfonation is proceeded after forming the interpenetrating polymer. Alternatively, the sulfonation of the hyper-branched polymer could be proceeded before the formation of the interpenetrating polymer.
