Claim:
A compound having the following general formula (I): A-X 1 -L-(W) p —NO 2 (I) wherein: p is an integer equal to 1 or 0; A=R-T 1 -, wherein R has the following formula: T 1 =(CO) t or (X) t′ , wherein X=O, S or NR 1C , wherein R 1C is H or a linear or branched alkyl, having from 1 to 5 carbon atoms, t and t′ are integers and equal to zero or 1, with the proviso that t=1 when t′=0; t=0 when t′=1; X 1 =-T B -Y-T B1 - wherein T B and T B1 are equal or different; T B =(CO) when t=0, T B -X when t′=0, X being as above; T B1 =(CO) tx , or (X) txx , wherein tx and txx have the value of 0 or 1; with the proviso that tx=1 when txx=0; and tx=0 when txx=1; X is as above; Y is selected from the following: wherein n3 is an integer from 0 to 3 and n3′ is an integer from 1 to 3; wherein n3 and n3′ have the above meaning, or wherein R 4 is hydroxy, hydrogen, or R 5 O— alkoxy wherein R 5 is a C 1 -C 10 linear, branched or cyclic alkyl group; and R 2 is a C 2 -C 10 linear or branched alkenylene group which can contain one or more double bonds, L=covalent bond, CO or X, X being as defined above; W=Y T O wherein Y T has the same meanings of Y as defined above, and Y T is equal to or different from Y.
