摘要
三氯硅烷的水解物经催化重排，制得了立体有序的全苯基有机硅树脂．以红外和核磁井振表征了其化学组成，以ｘ射线衍射初步分析了其立体有序性，以热重分析法等测定了其耐温世，发现该树脂５５０℃时失重为２．３７９％。６００℃时失重为５．１０５％，在有机硅树脂中尚未见耐温更高的报道。
Stereo-regular homo-phenyl organosilicone resin was prepared by means of catalytic rearrangementof hydrolysis product of phenyltrichlorosliane(PhSiCl_3).The chemical composition of the resin was charac-terized by means of IR and 1￣H-NMR. The stereo- regularity was analyzed by means of X- rdy,and theheat- resistant property was determined by means of TGA.It was found the weight loss was 2.379%at550℃and 5.105% at 600℃
