The diol is represented by the general formula (1) shown below; the polycarbonate resin and the polyester resin are polymers thereof; and the molded article and the optical element are formed of the polymers, wherein R1 and R2 each independently denote one of a hydrogen atom and an alkyl group having 1 or more and 6 or less carbon atoms; Q denotes one of an oxyethylene group, a thioethylene group and a single bond.

Diol, and polycarbonate resin or polyester resin

The present invention provides a crosslinker used for crosslinking a polymer material having, in the molecule thereof, a multiple bond reactable with a nitrile oxide, the crosslinker including a bifunctional nitrile oxide having an aromatic nitrile oxide derivative structure in which one hydrogen atom of an aromatic ring is substituted with a nitrile oxide group and all hydrogen atoms at an ortho-position of the nitrile oxide group are substituted with a substituent other than a nitrile oxide group, wherein two such aromatic nitrile oxide derivative structures are bonded to either two oxy groups of a di-oxy structure having the two oxy groups or two carbonyl groups of a di-carbonyl structure having the two carbonyl groups.

Crosslinker, crosslinked polymer material, and production method of the crosslinked polymer material

The present invention provides a production method of a crosslinkable polymer material which includes adding 2 -(glycidyloxy)-1-naphthonitrile oxide or 2-[5 -(ethoxycarbonyl)pentyloxy]-1-naphthonitrile oxide by an addition reaction to a polymer material having a multiple bond to which a nitrile oxide is added by an addition reaction so as to introduce a glycidyl group or an ethoxycarbonyl group into the polymer material.

Crosslinkable polymer material, crosslinked polymer material, and production method thereof

The present invention provides a production method of a modified polymer material produced by modifying a polymer material having in a molecule thereof a multiple bond that reacts with a nitrile oxide, includes reacting the polymer material with an aromatic nitrile oxide derivative having a substituent at an ortho-position of a nitrile oxide group of an aromatic nitrile oxide in which the nitrile oxide group is bonded to an aromatic ring.

Modified polymer material modified by nitrile oxide, and production method thereof
