Some illustrative polysiloxane polymers include polydimethylsiloxane, polydiethylsiloxane, polymethylethylsiloxane, polymethylphenylsiloxane, and polydiphenylsiloxane;(ii) Alkylmethylsiloxanes: These siloxane polymers generally will have the formula Me3SiO[Me2SiO]a[MeRSiO]bSiMe3, in which R is a hydrocarbon group containing 6-30 carbon atoms, Me represents methyl, and the degree of polymerization
