Title:
ウレタン結合を介してラジカル重合性基が導入された機能性微粒子と、それを含む医科歯科用硬化性組成物
Document Type and Number:
Japanese Patent JP6928418
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve the problems in which: wettability or mechanical strength of an inorganic filler blended in a medical/dental curable composition is improved by surface treatment of a silane coupling agent; because the silane coupling agent generally uses γ-methacryloxypropyl trimethoxysilane, dehydration temperature at dehydration condensation has limitations, and sufficient mechanical strength and durability is not obtained because of fragile xerogel layer and hydrophilic property; and an inorganic filler is required in which there is no fragile xerogel layer, and excellent mechanical strength and durability is given when used as a medical/dental curable composition.SOLUTION: A functional fine particle is given in which radical-polymerizable group is introduced through urethane bond into hydroxyl group on an inorganic filler surface. The functional fine particle is given in which surface modification of the inorganic filler surface is performed by reaction among coupling organic compound including isocyanate group and one kind or more radical-polymerizable group in a molecule and/or organic compound including uretdione group and one kind or more radical-polymerizable group in a molecule.SELECTED DRAWING: None
