| titleOfInvention | Easily slidable medical material |
| abstract | PURPOSE: To obtain a medical material having both of excellent easy slidability and anti-thrombogenecity by fixing acidic polysaccharide to the hydrophilic copolymer, which is applied and fixed to a base material by a covalent bond, by an ionic bond or the covalent bond. n CONSTITUTION: In a method for fixing acidic polysaccharide to a hydrophilic copolymer, an ionic bond or a covalent bond is adapted. In the ionic bond method, it is pref. to bond the tertiary group or quaternary ammonium salt thereof of the hydrophilic copolymer to the acidic polysaccharide by the ionic bond. In the covalent bond method, the amino group, hydroxyl group and carboxyl group being the functional groups of the hydrophylic copolymer are bonded to the amino group, hydroxyl group and carboxyl group contained in the acidic polysaccharide or the epoxy group or formyl group introduced by reaction of said polysaccharide. The amount of the acidic polysaccharide fixed to the hydrophilic copolymer is different according to objective easy slidability or anti-thrombogenecity and there is no special limit but said amount is pref. 0.1wt.% or more by wt. of the hydrophilic copolymer and especially pref. selected within a range of 1-50wt.%. n COPYRIGHT: (C)1990,JPO&Japio |
