SULPHUR-COMPRISING POLYOL COMPOUND USABLE AS MONOMER FOR POLYURETHANE SYNTHESIS

摘要

A sulphur-comprising polyol compound, usable in particular as a monomer for the synthesis of a polyurethane by polycondensation with a polyisocyanate, corresponding to the formula: (I) HO-Z1-M1-Z3-(M2-Z2)n-OH in which: - Z1 and Z2, which may be identical or different, are an at least divalent linking group comprising at least one carbon atom; - "n" is an integer equal to 0 or 1; - the units "M1" and "M2", which may be identical or different, correspond to one of the formulae (II) hereinafter: (II-1) -CH(OH)-CH2-S-; (II-2) -S-CH2-CH(OH)-; (II-3) -CH(OH)-CH2-S-CH2-CH(OH)-; - Z3, which is an at least divalent linking group comprising at least three carbon atoms, is: o either an aliphatic or cycloaliphatic group, wherein at least one of the groups Z1, Z2 and Z3 comprises an ethylenic unsaturation; o or an aromatic group comprising at least one phenylene group.
