  • Patent number: 7335704
    Abstract: The present invention relates to novel functional norbornenes as initiators for radical polymerization, its polymer and a process for producing the same. More particularly, the novel functional norbornenes can be selectively polymerized by ring-opening metathesis polymerization or radical polymerization to obtain various polynorbornene derivatives or grafted copolymer materials. The polynorbornene derivatives and grafted copolymer materials not only exhibit excellent functional properties but also enhanced physical and chemical properties after modification. The polynorbornene derivatives and grafted copolymer materials disclosed in the present invention exhibit excellent heat resistance, transparency and water resistance. The present invention also deals with a process for producing such derivatives and materials having controllable molecular weight with narrow molecular weight distribution.

  • Patent number: 7276195
    Abstract: Shape memory polymers prepared by copolymerizing two monomers, which each separately produce polymers characterized by different glass transition temperatures in the presence of a multi-functional monomer whereby the copolymer formed is cross-linked during the polymerization to form a thermoset network. The transition temperature of the final polymers is adjusted by the ratio of the monomers selected, to from about 150° C. to about 270° C., while the degree of crosslinking controls the rubbery modulus plateau. The shape memory polymers can be processed as castable formulations in the form of bulk articles, coatings and films. The invention also relates to the articles of manufacture thereof and methods of the preparation and use thereof.
