Cyclic silane esters and their solvolysis products and processes for producing the cyclic silane esters and solvolysis products

摘要

New compounds are: (a) Cyclic organosilane esters of formula (I); (b) cyclic organyloxyorganosilane esters of formula (II); (c) hydrolysis products of (I) or (II), of formula äSi(O)(a+1)(R2)(2-a)CH2CHR3CH2 -ÄO(CHR3)xÜyOHün (III); and (d) alcoholysis products of (I) or (II), of formula Si(OR2)(a+1)(R2)(2-a)CH2CHR3CH3 -ÄO(CHR3)xÜyOH (IV). In (I)-(IV), R1 = hydrolysable group or R2; R2 = organyl group linked to a carbon (C) atom; R3 = hydrogen (H) or methyl (Me); x = 2-6; y = 0-60; z = 1-6; a = 1 or 2; n = 2-6. Also claimed is the use of acyclic olefinically unsaturated organohydridosilane esters of formula CH2=CR3CH2-ÄO(CHR3)xÜyOH (V) as cross-linking agents and adhesives for materials and/or as phase transfer agents.
