    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.

  • Publication number: 20140072912
    Abstract: Processes for preparing polyester resins as toner production components. The processes include reacting an organic diol and a cyclic alkylene carbonate to produce carbon dioxide (CO2) and a polyalkoxy diol. The carbon dioxide is reacted with an alkylene glycol or alkylene oxide to produce additional cyclic alkylene carbonate having the same chemical structure as the cyclic alkylene carbonate used to produce the polyalkoxy diol. The additional cyclic alkylene carbonate is added with the cyclic alkylene carbonate used to produce the polyalkoxy diol. The polyalkoxy diol can be reacted with an organic diacid or diester in preparing a polyester resin. To prepare a toner, the polyester resin can be contacted with at least one toner production component.
