Abstract: The polymer comprises units of formula (I) and of formula (Ibis), being comprised the molar ratio between units (I) and (Ibis) comprised from 1.0:0.2 to 1.0:0.8, and wherein R4 are independently selected from radicals of formula (II), (III), and (IV), R1 and R1? are independently selected from: —H, (C1-C20)alkyl, (C5-C14)aryl, —OR5, —(CO)R6, —O(CO)R7, —(SO)R8, —NH—CO—R9, —COOR10, —NR11R12, —NO2, and halogen; R2, R2?, R3, and R3? are —H; P is a polymeric chain, R5 to R12 are independently selected: —H, (C1-C20)alkyl, and (C5-C14)aryl;R13 and R14 are independently selected from (C1-C5)alkyl, and (C5-C14)aryl;, m is from 3 to 4; n is from 1 to 2; and p is from 1 to 2 provided that n+m+p sums 6; the polymer comprising from 5 to 25 weight % of urea moieties, and having H-bonding and pi-pi staking interactions between the urea groups, and a tensile strength comprised from 3 to 15 MPa.
