• R1 are identical or different and are hydrogen or a monovalent, optionally substituted hydrocarbyl radical,
• R2 are identical or different and are monovalent, optionally substituted, aromatic hydrocarbyl radicals bonded via a ring carbon atom to silicon,
• a is 0, 1, 2 or 3,
• b is 0, 1, 2 or 3, and
• c is 0 or 1,
• with the proviso that
• the sum a+b+c is less than or equal to 3,

• in more than 10% of all units, c is 1,
• (A2) organosilicon compounds comprising units of the formula
• Ra′(R1O)b′R2c′SiO(4-a′-b′-c′)/2 (II),
• in which
• R, R1 and R2 have the definition stated for them above,
