  • Patent number: 11945927
    Abstract: [Problem] An object of the present invention is to provide a foam including a thermoplastic resin and rubber as a main component, in which a micronized product of a cellulose fiber is uniformly dispersed, and uniformity and mechanical properties are excellent. [Solution] A foam includes a modified cellulose fiber (A) covalently bonded with a diene-based polymer, a thermoplastic resin and/or rubber (B), and a diene-based polymer (C) having a functional group capable of covalently bonding with a cellulose fiber, in which the fiber (A) is micronized, the fiber (A) has a content of 0.05 to 20% by mass, and the thermoplastic resin and/or rubber (B) has a glass transition point of ?130° C. to 120° C.

  • Patent number: 10945997
    Abstract: An object of the invention is to obtain a preparation which shows enhanced effectiveness and safety compared to tacrolimus, has the concentration in blood maintained at a constant level without individual differences, whereby the control of the amount of administration depending on the blood kinetics (blood trough concentration) becomes unnecessary. The present invention relates to a polymeric derivative of tacrolimus, in which a polyethylene glycol segment and an alcoholic hydroxy group of tacrolimus are bonded to side-chain carboxy groups of a polyaspartic acid derivative.

  • Publication number: 20180334540
    Abstract: A problem of the present invention is to obtain a preparation which shows markedly enhanced effectiveness and safety by exhibiting high accumulability at diseased areas and having the blood concentration maintained at a constant level without individual differences, and for which the control of the dosage depending on the blood kinetics (blood trough concentration) becomes unnecessary. The invention relates to a polymeric derivative of tacrolimus including a copolymer of a polyethylene glycol segment and a polymeric moiety, in which a carboxy group in a side chain of the copolymer is bonded to an alcoholic hydroxy group of tacrolimus.
