Karstedt Catalyst – Catalyzed stepgrowth co-polyaddition of 1,9-decadiene and 1,1,3,3-tetramethyldisiloxane

Low to medium molecular weight H–Si-terminating and alkyl–Si-terminating co-polyadducts of 1,9-decadiene and 1,1,3,3-tetramethyldisiloxane have been synthesized. Molecular weight determination from 1H NMR data is described. Product features indicate that this novel class of siloxane-modified paraffins offers quite interesting properties.
