methyl carbamate weighing 75 g, added to the with a thermometer, a condensing tube, constant pressure the gasket funnel and of the mechanical stirring four flasks, heating to 60 °C molten. At this temperature into the inert gas, 3-chloropropyltrimethoxysilane 198 g, drop increases of about 2 h. After dropping, the temperature rising to 120 °C insulation 3 h. The temperature and control the stirring speed, the mixture obtained in the solid salt removed by filtration, to obtain clear filtrate, using iron powder as a catalyst, the rectification under the collection 120 °C/20 mmHg at poly isobutylene 155 g. By infrared spectroscopic analysis, as shown in Figure 1, in 2210 - 2276 cm - 1 is arranged at the tip of the absorption peak of strong, that the synthesis of the isocyanate group-propyl trimethoxy silane.
