Abstract
Alpha/alpha-prime/alkoxylated glycerol linear carbonic esters have formula (VI): where p is an integer higher than 1, x is an integer equaling 0 or 1 with x not always being zero, and M1 is hydrogen (H). Q1 can be a hydrocarbon aliphatic group, an amino hydrocarbon group or an oxygenated amino hydrocarbon group. G1 can be an α/α′-alkoxylated propyl group of general formula (II′): where R4, R5 and R6 are variously hydrogen (H), an alkyl or an amino-alkyl group having 1 to 5 carbon atoms, or general formula (VII): where R7 is a H or a hydrocarbon group having 1 to 6 carbon atoms, and m is an integer between 0 and 10 inclusive, and X is —O— or —NH—.
