| 摘要 |
The present invention relates to a dental composition with optimized viscosity and/or rheological behavior. The present invention provides a dental composition comprising: (d) at least one carboxylic acid functional polymer, (e) at least one acid derivative with stronger acidity than the carboxylic acid functional polymer (a), substituted with at least one polymerizable ethylenically unsaturated group, (f) 0.1 to 10 weight % of water,
wherein the carboxylic acid functional polymer (a) and the acid derivative (b) are present at least in an amount effective that the dental composition exhibit shear thinning and/or a viscosity from 1.0 to 20 Pa·s, when measured with a plate/plate geometry and at a shear rate of 0.5 to 1 s -1 . It further relates to the use of this dental composition and to a method for preparing a dental adhesive.
