- wherein:
- p represents an integer greater than 0,
- each R1, identical or different, represents a hydrogen atom or a C1-4 alkyl group,
- each R2, identical or different, represents a OH or NH2 group,
- each R3, identical or different, represents a C2-180 alkyl group, optionally substituted with one or more C1-4 alkyl substituents,
- L represents a C1-6 alkylene group, and
- n and m each independently represent an integer between 0 and 3200, m+n is between 1 and 3500, the ratio between m and n being between 0.01/1 and 0.1/1.
