Telechelic siloxanes with hydrogen-bonded polymerizable end groups. I. Liquid rubbers and elastomers
Publikováno v:
Journal of Applied Polymer Science. 117:756-766
Functional siloxanes are widely used in the synthesis of model networks used in rubber elasticity studies, and various functional siloxanes are also used in the synthesis of silicone rubbers. We present here the results of studies of two classes of t
