Polymers derived from norbornadiene and maleic anhydride and use thereof

A polymer comprising one or more distinct first repeating unit represented by formula (IA), each of said first repeating unit is derived from a monomer of formula (I):

• wherein:
• represents a position at which the bonding takes place with another repeat unit;
• each of R1, R2, R3 and R4 is independently selected from the group consisting of hydrogen, linear or branched (C1-C16)alkyl, hydroxy(C1-C12)alkyl, perfluoro(C1-C12)alkyl, (C6-C10)aryl(C1-C3)alkyl, —CO2R, halogen and a group of formula (A):
• where
• R is (C1-C6)alkyl or tri(C1-C6)alkylsilyl,
• Ra is selected from the group consisting of —(CH2)p—, —(CH2)q—OCH2— and —(CH2)q—(OCH2CH2)r—OCH2—, where p is an integer from 0 to 6, q is an integer from 0 to 4 and r is an integer from 0 to 3;
• one or more distinct second repeating unit represented by formula (IIA), said second repeating unit is derived from a monomer of formula (II):
• wherein:
• each of R5 and R6 is independently selected from the group consisting of hydrogen, linear or branched (C1-C9)alkyl and fluorinated or perfluorinated(C1-C9)alkyl;
• R7 is selected from the group consisting of hydrogen, linear or branched (C1-C9)alkyl, fluorinated or perfluorinated(C1-C9)alkyl,
• and —(CH2)a—(O—(CH2)b)c—O—(C1-C6)alkyl, where a, b and c are integers from 1 to 4;
• and
• one or more distinct third repeating unit represented by formula (IIIA), said third repeating unit is derived from a monomer of formula (III):
• wherein:
• each of R8 and R9 is independently selected from the group consisting of hydrogen, methyl, ethyl and linear or branched (C3-C9)alkyl;
• R10 is selected from the group consisting of hydrogen, methyl, ethyl, linear or branched (C3-C16)alkyl, (C5-C9)cycloalkyl, (C6-C10)aryl and (C6-C10)aryl(C1-C4)alkyl;
• and wherein molar amount of repeating unit of formula (IIIA) is at least 3 mole percent.
