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