ABSTRACT:
New alkylpolyether siloxanes are prepared by reacting an unsaturated ether with alkylhydrido siloxanes such as (i) comonomers RSi(OSiMe.sub.2 H).sub.3, (ii) oligomers (HMe.sub.2 SiO).sub.2 --Si(R)--O--Si(R)--(OSiMe.sub.2 H).sub.2, and (iii) higher molecular weight siloxane species RSi[(OSiMe.sub.2).sub.x OSiMe.sub.2 H].sub.3 and [HMe.sub.2 SiO(Me.sub.2 SiO).sub.x ].sub.2 Si(R)O(R)Si[(OSiMe.sub.2).sub.x OSiMe.sub.2 H].sub.2. R is a C.sub.2 to C.sub.18 straight-chain or branched-chain alkyl substituent.
