摘要：
The crystalline morphology of poly(dimethylsiloxane) was studied using a scanning electron microscope equipped with a cold stage. Samples of two different molecular weights were used. In both cases, spherulitic morphology is seen, from -70 degreesC, with spherulites of about 100 mu in size. Small single crystals of about a micron in size are also seen. and these are attributed to the presence of cyclics. (C) 2002 Published by Elsevier Science Ltd.
