Abstract
The invention relates to synthesis of polymer polyol initiated by virtue of a photoinitiator. The polymer polyol is prepared from the following raw materials in parts by weight: 70-80 parts of basic polyether, 10-15 parts of styrene, 10-15 parts of acrylonitrile and 0.1-0.5 parts of photoinitiator. The synthesis method comprises the following steps: (1) uniformly mixing the basic polyether, the styrene, the acrylonitrile and the photoinitiator, thereby obtaining a mixture; (2) allowing the mixture to continuously pass through the photoinitiator and continuously pass through ultraviolet irradiation, allowing the mixture to enter a spray reactor after passing through the photoinitiator, carrying out an emulsion grafting reaction, entering a tank reactor, carrying out an aging reaction, and obtaining a finished product after the reaction is ended. The product prepared by the method is small in smell, low in viscosity, safe, environment-friendly and low in energy consumption. Meanwhile, the preparation method is simple, easy to operate and low in cost, so that the product has higher market competitiveness.
