1. A silicone material comprising a material obtained via reaction between:
at least one organopolysiloxane A of mean molar mass (Mn) of less than 70000 g/mol, comprising siloxyl units (I.1) and (I.2):

OG Complex Work Unit Math
where:
a=1 or 2,
b=0, 1 or 2,
a+b=1, 2 or 3,
c=0, 1, 2 or 3,
the symbols Y, the same or different, represent a functional group of formula (I.3):

E is an aliphatic, cycloaliphatic or aromatic divalent hydrocarbon radical having 1 to 30 carbon atoms;
if present, G is an aliphatic hydrocarbon radical having 1 to 10 carbon atoms, monovalent when i=0 or divalent when i=1;
Z1, the same or different, is a monovalent hydrocarbon radical having 1 to 30 carbon atoms and optionally comprising one or more unsaturations and/or one or more fluorine atoms or a hydroxyl group;
Z2, the same or different, is a monovalent hydrocarbon radical having 1 to 30 carbon atoms and optionally comprising one or more unsaturations and/or one or more fluorine atoms, a hydroxyl group, or radical —OR1 where IV is a linear or branched C1-C10 hydrocarbon radical;
said organopolysiloxane A comprising per molecule:
