• 12
• in which R1, R2, R3, X, Y, m and n have the following meanings:
• R1=a linear or branched C1 to C20 alkyl or C6 to C14 aryl radical;
• R2=a hydrogen, a linear or branched C1 to C5 alkyl or phenyl radical;
• R3=a linear or branched C1 to C8 alkylene radical, phenylene or is absent;
• Y=oxygen, C1 to C8 alkylene or is absent;
• m=0 or 1;
• n=1 or 2;
• provided that Y=0, m=0 and R3=absent cannot be true at the same time and
• further provided that
• for m =1 and n=1
• X=hydrogen or a linear or branched C1 to C3 alkyl radical or a C6 to C14 aryl radical;
• for m=1 and n=2
• X=a linear or branched C1 to C10 alkylene, C6 to C10 arylene, C7 to C20 arylalkylene radical or a chemical bond which links together two radicals with the structure of formula (I) in brackets,
• the individual radicals being able to be substituted or unsubstituted.
