Silicone oligomers with heigher alkoxy groups
An oligomer of the formula: [R 3 SiO ½ ] m [O ½ Si(R 2 )O ½ ] n [SiO {fraction (3/2)} R] o [SiO {fraction (4/2)} ] p (I) wherein each R is selected individually from the group consisting of R 1 , -OR 2 and -OR 3 ; each R 1 is independently a substituted or unsubstituted hydrocarbon group; each R 2...
