摘要： PROBLEM TO BE SOLVED: To obtain a polymerizable dental material that scarcely cause contraction at the time of polymerization and is suitable for obtaining a composite material of high mechanical strength and hardness by combinational use of a specific norbornene silane compound and a specific mercaptosilane compound. SOLUTION: This polymerizable dental material comprises a combination of a hydrolyzable and polymerizable silicic condensate of norbornene silane of formula I [R is H or an alkyl; R is an alkyl, an alkenyl, etc.; R is not existing or an alkylene, etc.; R is not existing or an alkylene, etc.; R is an alkyl, etc.; R is CO-S-R (R is an alkylene, etc.); X is a hydrolyzable group; X is O, etc.; (x), (a) and (b) are each 1-3] and a hydrolyzable and polymerizable silicic condensate of mercaptosilane of formula II [R is an alkylene, etc.; R is an alkylene, etc.; R is an alkyl, etc.; X is a hydrolyzable group; (g) and (h) are each 1-3; (f) is 1-4]. Into this system, furthermore a compound of formula III [R is an alkyl, etc.; X' is H, a halogen, etc.; Z' is a mercapto, etc.; (k) and (m) are each 0-3] may be added.

摘要： PROBLEM TO BE SOLVED: To obtain a dental material containing a polymerizable binder and a filler and useful as a cement material or a filling material. SOLUTION: This dental material contains at least one kind of polymerizable binder and at least one kind of filler. The dental material contains a redox initiator system for radical polymerization. The initiator system contains an initiator and an activator. The filler is the homogeneous mixture of the filler first portion capable of being mixed with the initiator, the filler second portion capable of being mixed with the activator, and the filler third portion not containing an initiator system component. The filler third portion is preferably contained in an amount of 20-90 wt.% based on the total weight of the filler. The filler first portion is preferably contained in an amount of 1-20 wt.% based on the total amount of the initiator or the activator and the filler, and/or the filler second portion is preferably contained in an amount of 1-20 wt.% based on the total amount of the initiator or the activator and the filler.

摘要： PROBLEM TO BE SOLVED: To obtain the subject compound having plural vinylcyclopropane structures and capable of forming a cross-linkable polymer not containing a hydrolytically cleavable group in the main chain, especially a polymer useful as a component for dental materials. SOLUTION: A compound of formula I [R is H, a (substituted) 1-12C alkyl, a (substituted) 6-14C aryl; (n) is 2-6; R is an n-substituted 1-20C alkylene which may contains O, S, etc., in the chain, an n-substituted 6-14C arylene; Y is CO, CO-O, CO-S, SO2 , etc.; X is a single bond, Y]. For example, 1,1,1-tris[(2- vinylcyclopropane-1-carboxylic acid methyl ester-1-carbonyloxy)methyl]propane. The compound of formula I is obtained by reacting a compound of formula II with a compound of the formula: Zn R (Z is a releasable group).
