摘要

Prodn. of reaction prods. (I) of saccharides and bifunctional cpds. comprises mixing the starting materials and subjecting the mixt. to pressure. Also claimed are polysaccharide derivs. of formula (Ia)-(In): Sa-NH-CO-S-(CHR')n-Si(R")2OR' (Ia) Sa-O-Si(R")2-(CHR')n'-R (Ib) Sa-O-CH=CH-(CHR')n-Si(R")2OR' (Ic) Sa-O-Si(R")2-(CHR')n-COOR' (Id) Sa-OCH2-CHOH-CHR'-O-(CHR')n-Si(R")2OR' (Ie) Sa-O-CO-NH-(CHR')n-Si(R")2OR' (Ih) Sa-O-CO-(CHR')n'-CR'=CHR' (Ii) Sa-O-CH2-CHO-CHR'-O-CO-CR'=CHR' (Ij) Sa-O-Si(R'")2- (CHR')n-CR'=CHR' (Ik) Sa-O-CR'=CHR' (Im) Sa-O-CO-CR'=CHR' (In) Sa = a polysaccharide residue; R = opt. substd. 1-6C alkoxy, 2-6C alkenyl or 1-6C acyloxy, where acyloxy opt. contains a vinyl gp.; R' = opt. substd. 1-6C alkyl or aryl, or C-bonded R' may also be H; R" = R' or OR'; R" ' = R' or halogen; n = 1-6; n' = 0-6.
