Claims11
Oligomeric compounds obtained by self-condensation of a compound of formula (I)
- in which R1 and R2 are C1-C22 alkyl, isoalkyl or cycloalkyl groups.
Compounds of formula (II)
- wherein:
- Y and Z are —O— or —NH— with the proviso that they are not both —NH—
- and
- when Y and Z are both —O—, R, R1, R2, R3 and R4 are the same and are hydrogen, C1-C22 straight or branched alkyl or cycloalkyl groups;
- when Y is —O— and Z is —NH—, R is a C1-C22 straight or branched alkyl or cycloalkyl group which can be the same or different from R1, R2, R3 or R4 groups which are the same and are selected from hydrogen, C1-C22 straight or branched alkyl or cycloalkyl groups;
- when Y is —NH— and Z is —O—, R4 is a C1-C22 straight or branched alkyl or cycloalkyl group which can be the same or different from R, R1, R2 and R3 groups which are the same and are selected from hydrogen, C1-C22 straight or branched alkyl or cycloalkyl groups.
