摘要:
A medical material having a surface which is safe and excellent in stability with the lapse of time and has a high durability as needed in establishing a long-lasting surface lubricity in a wet state and an excellent compatibility with blood, and a method for producing the same. These materials are obtained by forming a coating layer with a coating material containing a polymeric substance (A) having a heterocyclic group represented by the formula (1) on at least a part of a surface of a medical material base, and then ring-opening the heterocyclic group remaining in the coating layer by a nucleophilic compound (N): wherein X represents O, NH or S; and R1 represents H or CH3.
摘要:
A random copolymer obtained by polymerizing a monomer composition comprising allylamine or a salt thereof and a monomer bearing a phosphorylcholine-like group, comprising 0.01 to 9 mole % of constituent units (A1) derived from allylamine or a salt thereof and 91 to 99.99 mole % of constituent units (A2) derived from a monomer bearing a phosphorylcholine-like group, and having a number-average molecular weight of 50000 to 5000000. This copolymer is excellent in biocompatibility, can be easily fixed on the surfaces of substrates, and exhibit good surface lubricity when formed into films, thus being useful as medical material.

摘要:
A high purity polysaccharide containing hydrophobic group is produced by a process involving a first process step of producing an isocyanate group-containing hydrophobic compound, wherein one mole of a hydroxyl group-containing hydrocarbon having 12-50 carbon atoms or of a sterol is reacted with a diisocyanate represented by OCN—R1—NCO in which R1 is a hydrocarbyl of 1-50 carbon atoms, a second process step of producing the polysaccharide containing hydrophobic group composed of the hydrocarbon group of 12-50 carbon atoms or of the steryl group, wherein the isocyanate group-containing hydrophobic compound obtained in the first process step is reacted with one or more polysaccharides, and a purification step in which the reaction product in the second process step is purified using a solvent based on a ketone.

A pedal holding device includes: a four-bar linkage including four links and four joints that connect the four links. Two of the four joints serve as two fixed joints that are provided in a main body of the pedal holding device. One of the four links, which is not connected to the two fixed joints, serves as an intermediate link that is provided with a pedal, such that the pedal is not pivotable relative to the intermediate link. One of four internal angles each defined by corresponding adjacent two of the four links becomes not smaller than 180° at at least one moment in a period of movement of the pedal from its rearward end position to its forward end position. Non-adjacent two of the four links intersect with each other apparently when the pedal is positioned in one of the forward end position and the rearward end position.
摘要:
There is disclosed a styrenic resin pellet having a length in the range of 2 to 100 mm which comprises a (A) styrenic polymer having syndiotactic configuration and containing a polar group and at least 10% by weight of a (B) glass fiber which is surface-treated with a coupling agent, is impregnated with the styrenic polymer, and has a length equal to the length of the pellet. The styrenic resin pellet is imparted with excellent moldability and improved in general physical properties such as impact resistance and heat resistance, thereby making itself well suited to the raw material for producing molded articles excellent in practical characteristics such as tensile creep at elevated temperatures higher than the glass transition temperature and vibrational fatigue characteristics at elevated temperatures.
