| titleOfInvention | Ring-opened polynorbornenes |
| abstract | The invention provides a ring-opened polynorbornenenthat is relatively low in birefringence, has specificnwavelength dependency about birefringence and is excellentnin transparency and heat resistance. n[Solving means] The polymer of the present invention has anstructural unit (I) of the general formula (I): n[Chemical formula 1]n nwherein in the general formula (I), m and n are integers ofn0 to 2, X 1 is an ethylene or vinylene group, R 1 and R 2 arenindividually a hydrogen atom or a substituted ornunsubstituted hydrocarbon group having 1 to 30 carbon atoms,nand R 3 is a group of the general formula (I-1) or (I-2), innwhich in the general formulae (I-1) and (I-2), R 11 to R 27 nare individually a hydrogen atom; a halogen atom; ansubstituted or unsubstituted hydrocarbon group having 1 ton30 carbon atoms, which may have a linkage containing or notncontaining oxygen, sulfur, nitrogen and/or silicon atom(s); nor a polar group, p and q in the general formula (I-1) arenindividually 0 or a positive integer, with the proviso thatnwhen both p and q are 0, R 12 and R 15 , or R 19 and R 15 may benbonded to each other to form a carbon ring or heterocyclicnring, and the carbon ring or heterocyclic ring may beneither a monocyclic structure or a polycyclic structure,nand s in the general formula (I-2) is 0 or a positiveninteger. |
