Polyether based preparations and the use thereof

摘要

The invention relates to preparations, containing (A) 30 to 56 wt.-% aziridino polyethers with a cyclic polyether content lower than 5.0 wt.-%; (B) 30 to 45 wt.-% compounds which effect a softening of the cured dental materials; (C) 10 to 15 wt.-% filler; (D) 4 to 10 wt.-% further active ingredients; with the provisos that the weight ratio between constituents (A) and (C) to the compounds of constituent (B) is 1.2 to 2.1; constituent (B) consists of compounds with molar masses lower than 500 g/mol (B1) and of trisacylesters of glycerol of non-animal origin with molar masses between 500 to 2000 g/mol (B2) as well as of compounds with molar masses greater than 2000 g/mol (B3) and the weight ratio between (B1) and (B3) is 1:0.8 to 1:2.3, as well as their use.
