Claim 18:
19. The composition as claimed in claim 18, in which the polydiol compound A1 is a copolymer resulting from the copolymerization:
of at least one first monomer M1 of general formula (I):, , in which:
R1 is chosen from the group consisting of —H, —CH3 and —CH2—CH3;
y is an integer equal to 0 or 1;
Y represents a divalent linking group chosen from C1-C20 alkyl chains, optionally comprising one or more ether —O— bridges;
X1 and X2, which are identical or different, are chosen from the group consisting of hydrogen, tetrahydropyranyl, methyloxymethyl, tert-butyl, benzyl, trimethylsilyl and t-butyldimethylsilyl;
or else
X1 and X2 form, with the oxygen atoms, a bridge of following formula:, in which:
the stars (*) symbolize the bonds to the oxygen atoms,
R′2 and R″2, which are identical or different, are chosen from the group consisting of hydrogen and a C1-C11 alkyl group;
or else
X1 and X2 form, with the oxygen atoms, a boronic ester of following formula:, in which:
the stars (*) symbolize the bonds to the oxygen atoms,
R′″2 is chosen from the group consisting of a C6-C30 aryl, a C7-C30 aralkyl and a C2-C30 alkyl;
with at least one second monomer M2 of general formula (II):, in which:
R2 is chosen from the group consisting of —H, —CH3 and —CH2—CH3,
R3 is chosen from the group consisting of —C(O)—O—R′3; —O—R′3; —S—R′3 and —C(O)—N(H)—R′3, with R′3 a C1-C30 alkyl group.
