    摘要： The present disclosure provides compositions comprising:



    a) a copolymer prepared by a method comprising polymerizing in the presence of a metathesis catalyst:

    i) a first monomer, wherein each instance of the first monomer is independently of the formula:












    or salt thereof;

    ii) a second monomer, wherein each instance of the second monomer is independently of the formula:












    or a salt thereof;

    iii) optionally a third monomer, wherein the third monomer is different from the first monomer and the second monomer; and
    iv) optionally a reprocessing catalyst; and


    b) optionally the reprocessing catalyst;
    wherein the reprocessing catalyst is a Brønsted acid, Lewis acid, Brønsted base, Lewis base, or a salt thereof;
    provided that the composition comprises at least one of the reprocessing catalyst of iv) and the reprocessing catalyst of b).
    The compositions may be reprocessed (e.g., remolded) under elevated temperature and/or elevated pressure.
