Abstract:
Certain polymer dispersions interact with calcium hydroxide and form precipitates. The amount thereof increases until a specific limit above which the volume of precipitate becomes constant. This could be illustrated photographically. By x-ray diffraction analysis, it was shown that increasing the amount of polymer gradually decreased the height of the diffraction peaks of calcium hydroxide, and finally only a broad shoulder was observed. In microscopic analysis, no typical distinct crystals of calcium hydroxide could be seen. A mechanism for the influence of the polymer on the crystallization process is proposed.
