Dental composition containing a prepolymer and a crosslinker, process for producing and use thereof

摘要

The invention relates to a curable composition comprising
prepolymer (A) having the formula:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ(L-C(=O)-O-) n P
wherein
L
is a group represented by the following formula
with with the N,N' bridging unit being part of a heterocyclic quasi-aromatic ringsystem, optionally containing O, N or S, preferably an azolide,
P
is a prepolymer backbone having a molecular weight (Mn) of at least 500,
n
is at least 2,
and crosslinker (B) comprising at least 3 nucleophilic groups. The curable composition can be used for coating, sealing, moulding, adhering, making impressions, especially in the dental field.
