New alkylpolyether siloxanes are prepared by reacting an unsaturated ether with alkylhydrido siloxanes such as (i) comonomers RSi(OSiMe2H)3, (ii) oligomers (HMe2SiO)2-Si(R)-O-Si(R)-(OSiMe2H)2 and (iii) higher molecular weight siloxane species RSi[(OSiMe2)xOSiMe2H]3 and [HMe2SiO(Me2SiO)x]2Si(R)O(R)Si[(OSiMe2)xOSiMe2H]2. R is a C2 to C18 straight-chain or branched-chain alkyl substituent.
