其实你所講聚合物polymers是可以用以Silicone base vs.Carbon base polymers來講 :
C is organic (plant based) Si is inorganic(mineral-baese)
C forms covalent bonds Si forms hybrid ionic/covalent bonds
CO2 is a simple gas SiO2 is a complex solid polymer
CCl4 is a reasonably stable gasSiCl4 is highly reactive cpd
以上已指出C與Si基本分別 , 而由於其monomers而形成polymers就有很大分別了 . The Si-O bond has higher bond energy than C-O bond.
The Si-O bond is longer & flatter than C-Obond.
The Si-O bond has a lower barrier to rotation than C-O bond &
higher free volume .
