Publication number: 20140242623Abstract: 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.Type: ApplicationFiled: May 10, 2011Publication date: August 28, 2014Inventors: Scott T.

Publication number: 20100167075Abstract: Methods and compositions are provided for protecting exterior surfaces of automobiles and other products, or components of products, against abrasion, abrasive dust, water, acid rain, etc. The methods involve applying to a surface a protective coating composition comprising a polyvinyl butyrate emulsion and a relatively inert extender. The emulsion is dried to form a water-resistant protective coating that can be removed from the underlying surface by peeling when no longer desired.Type: ApplicationFiled: November 8, 2007Publication date: July 1, 2010Inventor: Robert Mesa

Patent number: 7638569Abstract: The present invention is an injection-molded gear made of a polyacetal resin composition comprising a polyacetal and a filler having a particular shape and particle diameter. An object thereof is to provide a gear which has durability and is excellent in the balance between dimensional accuracy and rotation transmission accuracy. Specifically, the gear is an injection-molded gear made of a polyacetal resin composition comprising more than 5 and less than 100 parts by mass of a filler (II) having a particle size distribution satisfying a particular expression and an average aspect ratio (L/D), i.e., a ratio of an average major-axis length (L) of the particles to an average minor-axis length (D) of the particles, of less than 3 and 0 or less than 10 parts by mass of an organic acid (III) based on 100 parts by mass of a polyacetal (I), characterized in that the gear comprises 10% or less of aggregates of the filler (II) having an aggregate diameter of 3 ?m or more.Type: GrantFiled: July 19, 2006Date of Patent: December 29, 2009Assignee: Asahi Kasei Chemicals CorporationInventors: Kenya Sonobe, Miho Sonobe

Patent number: 7625501Abstract: An improved color-converting photoluminescent film that provides visible light emission in the red to green portion of the visible spectrum when excited by blue light. The color-converted photoluminescent film of the invention is patternable and has improved luminous efficiency and stability and is suitable for use in electroluminescent displays. The film comprises a mixture of a clear UV curable resin and photo-initiator which does not absorb blue light; and fluorescent pigment particles, wherein a molecular additive is optionally provided in to either or both of the pigment particles and curable resin. The mixture is screen printed onto a substrate to form a film and UV cured.Type: GrantFiled: May 17, 2005Date of Patent: December 1, 2009Assignee: Ifire IP CorporationInventors: Maizhi Yang, John Wesley Moore, Abdul M.
