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 H-1 NMR data is described. Product features indicate that this novel class of siloxane-modified paraffins offers quite interesting properties.
