    • Our experience indicates that the elemental analyses for this type of polymer are not very reproducible. This problem could arise from the tendency of carbosilanes to form silicon carbide (or oxycarbide) on pyrolysis, rendering the complete combustion of the carbon difficult. For example, all of the analyses given above were done at Galbraith Laboratories, Inc., Knoxville, TN. Several of the same samples were also sent to Guelph Chemical Laboratories Ltd., Guelph, Ontario, Canada. The results are as follows, for allyl-substituted HBPSE: C, 61.72; H, 9.54. for butyl-substituted HBPSE: C, 66.11; H, 13.05. for phenyl-substituted HBPSE: C, 79.12; H, 6.17. Obviously, the analyses from Galbraith Laboratories give the most conservative estimate of the degree of substitution.
