    Abstract: Poly(propylene fumarate) is copolymerized with poly(caprolactone) diol to produce a block copolymer of poly(propylene fumarate) and poly(caprolactone). The biocompatible and bioresorbable block copolymer of poly(propylene fumarate) and poly(caprolactone) is useful in the fabrication of injectable and in-situ hardening scaffolds for tissue and/or skeletal reconstruction. The block copolymer can be crosslinked by redox or photo-initiation, with or without an additional crosslinker. Thus, the copolymer is both self-crosslinkable (without the use of any crosslinkers) and photocrosslinkable (in the presence of photons such as UV light).

    Abstract: The present invention provides a closed-cell foamed rubber sheet whose sealability is less likely to decrease even after long-time use and which has excellent water resistance. The closed-cell foamed rubber sheet of the present invention comprises a rubber-based resin, and is provided by the steps of: providing a foamable resin composition containing the rubber-based resin and a foaming agent; irradiating the foamable resin composition with ionizing radiation to cross-link the foamable resin composition; and foaming the cross-linked foamable resin composition. In the case where the foamable resin composition further contains 0.5 parts by weight or more of a powdery additive other than the foaming agent per 100 parts by weight of the rubber-based resin, the rubber-based resin preferably contains a rubber-based resin ingredient which is in a liquid state at normal temperature.

    Abstract: The invention relates to an active ingredient composition which has a high content in thermosensitive foaming agents and one or more polyolefin resins, the portion which is larger in quantity being a metallocene and optionally the remaining resins being polar or nonpolar nonmetallocene polyolefin resins. All polyolefin resins add up to at least 10% by weight of the formulation and have a melting point between 80 and 170° C. The reduced dust active ingredient composition according to the invention is used for the masterbatch production of foamed plastics.
