[Material-testing studies for the rationalization of the technology of stomatological cold curing-plastics].

Materials scientific studies on the rationalization of the processing of stomatological cold-curing plastics. Hydropneumatic overpressure polymerization leads to a considerable rationalization of the processing of stomatological cold-curing plastics, but its effects on the course of polymerization and the properties of the polymerizate are yet not sufficiently elucidated. For this reason, the author studied in several test series the effects of various processing parameters (flask and overpressure vessel; varying mixing ratios, pressures and temperatures) on the polymerization of Kallocryl-AS, a cold-curing plastic. The results obtained indicate that, under certain processing conditions, overpressure polymerization of cold-curing plastics may be recommended from the viewpoint of materials science.
