Abstract:
Dental composition comprising (a) at least two di- or polyepoxides having 2 to 5 epoxide groups and having a molecular weight of from 200 to 700 Da, or a macromonomeric reaction product obtainable by reacting the diepoxide with a dicarboxylic acid in a molar ratio [diepoxide]/[dicarboxylic acid] of at least 2; (b) one or more primary monoamines and/or disecondary diamines; (c) optionally one or more aliphatic polyamines; (d) a particulate filler, wherein the molar ratio of epoxide groups in component (a) to the N—H bonds in component (b) and (c) [epoxide (a) ]/[N—H (b),(c) ] is in the range of from 0.9 to 1.1; wherein the di- or polyepoxide having 2 to 5 epoxide groups is a compound of the following formula (I):   A(BZ m ) n    (I) wherein A represents an n-valent organic moiety optionally having 1 to 10 heteroatoms selected from oxygen atoms and sulfur atoms; and B represents an m+1-valent organic moiety, Z is an epoxide group which may have a substituent, m which are independent from each other represent an integer of at least 1; and n is an integer of from 1 to 5; wherein the m are selected so that 2 to 5 epoxide groups are present; wherein the composition does not contain any 2,2-bis-(4-hydroxyphenyl)-propane, or 2,2-bis-(4-hydroxyphenyl)-methane.

Claim (Index 1):
Dental composition comprising.\n (a) at least two di- or polyepoxides having 2 to 5 epoxide groups and having a molecular weight of from 200 to 700 Da, or a macromonomeric reaction product obtained by reacting the diepoxide with a dicarboxylic acid in a molar ratio [diepoxide]/[dicarboxylic acid] of at least 2; (b) one or more primary monoamines and/or disecondary diamines; (c) one or more aliphatic polyamines; (d) a particulate filler, wherein the molar ratio of epoxide groups in component (a) to the N\u2014H bonds in component (b) and (c) [epoxide(a)]/[N\u2014H (b),(c) ] is in the range of from 0.9 to 1.1; wherein the di- or polyepoxide having 2 to 5 epoxide groups is a compound of the following formula (I):\n A(BZ m ) n  \u2003\u2003(I) \n wherein A represents an n-valent organic moiety optionally having 1 to 10 heteroatoms selected from oxygen atoms and sulfur atoms; and B represents an m+1-valent organic moiety, Z is an epoxide group which may have a substituent, m which are independent from each other represent an integer of at least 1; and n is an integer of from 1 to 5; wherein the m are selected so that 2 to 5 epoxide groups are present; wherein the heteroatoms selected from oxygen atoms and sulfur atoms in groups A are present in ester bonds, ether bonds, thioether bonds or thioester bonds; and wherein the composition does not contain any of 2,2-bis-(4-hydroxyphenyl)-propane, 2,2-bis-(4-hydroxyphenyl)-methane, bisphenol-A diglycidyl ether, bisphenol-F diglycidyl ether, or butanediol diglycidyl ether.
