Storage solutions of silsesquioxane and siloxane polymers are obtained by means of a silicon containing solvent composition. The solution has at least one polymer having a formula of [(HSiO1.5)xOy]n, (HSiO1.5)n, [(HSiO1.5)xOy(RSiO1.5)z]n, [(HSiO1.5)x(RSiO1.5)y]n or [(HSiO1.5)xOy(RSiO1.5)z]n wherein x=about 6 to about 20, y=1 to about 3, z=about 6 to about 20, n=1 to about 4,000, and each R is independently H, C1 to C8 alkyl or C6 to C12 aryl. The solvent has the formula of (CH3)3Si-O-[Si(CH3)2]a-Si(CH3)3, (CH3CH2)Si-O-[Si(CH3CH2)2]a-SiCH3CH2)3, R3Si-O-[SiR'2]a-SiR3, [O-Si(CH3)2]b, [O-Si(CH3CH2)2]b or [O-SiR'2]n wherein a=0-5, b=3-5, and each R' is independently H or C1 to C8 alkyl.
