Abstract:
A hydrogenated ring-opening metathesis polymer comprising at least a structural unit (A) represented by the following general formula (1): wherein at least one of R1 to R4 is a substituent containing an acid cleavable group, and others are selected from hydrogen, an alkyl group having 1 to 20 carbon atoms, a halogen, a halogenated alkyl group having 1 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, an alkoxyalkyl group having 2 to 20 carbon atoms, an alkylcarbonyloxy group having 2 to 20 carbon atoms, an arylcarbonyloxy group having 7 to 20 carbon atoms, an alkylsulfonyloxy group having 1 to 20 carbon atoms, an arylsulfonyloxy group having 6 to 20 carbon atoms, a carboxy group, a hydroxy group, a carboxyalkyl group having 2 to 20 carbon atoms, or a hydroxyaklyl group having 1 to 20 carbon atoms; X1 is selected from â€”Oâ€”, â€”Sâ€”, â€”NR5â€” or â€”PR5â€” (R5 represents hydrogen or an alkyl group having 1 to 20 carbon atoms) and may be the same or different; and m represents 0 or an integer of 1 to 3; a structural unit (B) represented by the following general formula (2): wherein at least one of R6 to R9 is a substituent containing carboxy or hydroxy, and others are selected from hydrogen, an alkoxy group having 1 to 20 carbon atoms, an alkoxyalkyl group having 2 to 20 carbon atoms, an alkyl group having 1 to 20 carbon atoms, a halogen, a halogenated alkyl group having 1 to 20 carbon atoms, an alkylcarbonyloxy group having 2 to 20 carbon atoms, an arylcarbonyloxy group having 7 to 20 carbon atoms, an alkylsulfonyloxy group having 1 to 20 carbon atoms, or an arylsulfonyloxy group having 6 to 20 carbon atoms; X2 is selected from â€”Oâ€”, â€”Sâ€”, â€”NR10â€” or â€”PR10â€” (R10 represents hydrogen or an alkyl group having 1 to 20 carbon atoms) and may be the same or different; and n represents 0 or an integer of 1 to 3; and a structural unit (C) represented by the following general formula (3): wherein at least one of R11 to R14 is a substituent containing cyano or lactonyloxycarbonyl, and others are selected from hydrogen, a carboxy group, a hydroxy group, a carboxyalkyl group having 2 to 20 carbon atoms, a hydroxyalkyl group having 1 to 20 carbon atoms, an alkoxycarbonyl group having 2 to 20 carbon atoms, an alkoxycarbonylalkyl group having 3 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, an alkoxyalkyl group having 2 to 20 carbon atoms, an alkyl group having 1 to 20 carbon atoms, a halogen, or a halogenated alkyl group having 1 to 20 carbon atoms; X3 is selected from â€”Oâ€”, â€”Sâ€”, â€”NR15â€” or â€”PR15â€” (R15 represents hydrogen or an alkyl group having 1 to 20 carbon atoms) and may be the same or different; and 1 represents 0 or an integer of 1 to 3,wherein a constituent molar ratio of the structural unit (A)/(B) is from 1/99 to 99/1 and a constituent molar ratio of the structural unit (B)/(C) is from 30/70 to 100/0 and, furthermore, a ratio of a weight-average molecular weight Mw to a number-average molecular weight Mn, that is Mw/Mn is from 1.0 to 2.0.
