    Abstract: The present invention relates to innovative materials which can be crosslinked by means of two different crosslinking mechanisms, the first crosslinking mechanism being an irreversible crosslinking. The second crosslinking mechanism is a thermoreversible mechanism. As a result of this thermoreversible change in the arc length, properties of the crosslinked material can be decisively changed and controlled, including flexibility, elasticity and other mechanical properties, but also chemical properties, the gas permeability and vapor permeability and storage capacity of the network. In this way it would be possible, for example, to store energy sources such as fuels.

  • Patent number: 8147720
    Abstract: An aluminum chelate-based latent curing agent is provided which can cure a thermosetting epoxy resin at a relatively low temperature in a short period of time. A method for producing such an aluminum chelate-based latent curing agent, whose curing conditions can be relatively easily controlled, is also provided. The aluminum chelate-based latent curing agent is made latent by reacting a silsesquioxane-type oxetane derivative with an aluminum chelating agent in the presence of an alicyclic epoxy compound.

  • Patent number: 8123971
    Abstract: The invention relates to composites made of an elastic carrier medium comprising polynorbornene (PNR) and magnetisable particles which are polarized reversibly in a magnetic field. Thus the mechanical properties, such as e.g. storage modulus G? (describes the elastic behavior or the energy storage) and loss modulus G? (describes the viscous behavior or the energy dissipation), of such elastomer composites can be increased rapidly and reversibly within wide limits (up to approx. two orders of magnitude) as a function of an external magnetic field. Wide-ranging application possibilities are produced herefrom, e.g. for adaptive damping systems, in which the damping force can be adjusted via the strength of the magnetic field.

  • Patent number: 8088865
    Abstract: Provided is a method for producing a resin composition by melt-kneading a cyclic olefin polymer (A) having a glass transition temperature of from 60 to 200° C. and a flexible polymer (B) having a glass transition temperature of 0° C. or lower, wherein a part of the cyclic olefin polymer (A) is previously melt-kneaded with the flexible polymer (B) and a radical initiator (C) and then the remaining cyclic olefin polymer (A) is added thereto and melt-kneaded. The cyclic olefin polymer (A) is divided into two portions and added separately at two times, and accordingly, the mixture having a crosslinked structure may be diluted with the cyclic olefin polymer (A) not having a crosslinked structure, and the increase in the melt viscosity of the resin composition may be thereby prevented. A composition having good abrasion resistance and good melt shapability can be obtained.

  • Patent number: 7989571
    Abstract: Disclosed is a method for producing a norbornene monomer composition, a norbornene polymer produced using the norbornene monomer composition, an optical film including the norbornene polymer, and a method for producing the norbornene polymer. The method includes reacting a reaction solution that contains cyclopentadiene, dicyclopentadiene, or a mixture of cyclopentadiene and dicyclopentadiene, an acetate compound, and a solvent so that a content of an exo isomer is 50 mol % or more. Variables such as a reaction temperature, a reaction time, a molar ratio between reactants, and addition of a solvent are controlled so that the exo isomer is contained in content of 50 mol % or more. Accordingly, it is possible to industrially produce an acetate norbornene addition polymer by using the acetate norbornene monomer composition containing the exo isomer in content of 50 mol % or more.
