Title:
POLYURETHANE SYNTHESIS BY MEANS OF SELF-CONDENSATION
Document Type and Number:
WIPO Patent Application WO/2011/045546
Kind Code:
A3
Abstract:
The present invention relates to a compound with the following formula (I) where: R1 is particularly a straight or branched alkyl group, a is a single or double bond; R2 is particularly a hydrogen atom; R3 and R5 are a hydrogen atom when a is a single bond, and absent when a is a double bond; R4 is a hydrogen atom or an ORb group, where Rb is a hydrogen atom or an alkyl group including 1 to 12 atoms of carbon, and A1 is a divalent alkylene radical.
