Polysiloxanes comprising methylene-bonded polar groups

The invention relates to polysiloxanes of general formula (1): [A-SiR2-O1/2]a[B-SiRO2/2]b[C-SiO3/2]c[SiO4/2]d, where A, B and C represent R or -CR1R2-X, X represents O-Ro1, S-Ro2, S(O)Ro3, SO2-Ro4, CN or NO2, R1 and R2 represent a hydrogen group or a C1-C18 hydrocarbon group, Ro1, Ro2, Ro3 and Ro4 represent a C1-C18 hydrocarbon group, R is defined as per claim 1 and b is a number with a value of at least 11, with the proviso that if Y represents a group F, Br, I, SH, then m has the value 1 and if Y represents a group Cl, OR`, OOC-R`, then m has the value 0, that o+p>=1, that 0.1 - 100 % of units A, B and C represent -CR1R2-X, that a + b + c + d equals a number from 11 - 10,000 and that c + d < 0.2 * (a + b + c + d). The invention also relates to a method for producing the intermediate products of general formula (5): Ro1O-CH2-Si(OAlk)(3-t)Ra t, where Ro1, Alk, t and Ra are defined as per claim 7. 本发明涉及通式(1)的聚硅氧烷：[A-SiR-O][B-SiRO][C-SiO][SiO]，其中A、B、C为R或-CRR-X，X为O-R、S-R、S(O)R、SO-R、CN、NO，R和R为氢基团或C-C烃基，R、R、R和R为C-
