Abstract
Disclosed is a curable resin which comprises at least one polymer selected from polymers each independently having a polymer chain represented by the following formula (I): ##STR1## wherein A to F are monomer units constituting a main chain of the polymer and are arranged in any order, and a to f are, respectively, wt % of A to F, based on the total weight of A to F; wherein each A is independently selected from cyclic olefin monomer units having no reactive group, each B is independently selected cyclic conjugated diene monomer units having no reactive group, each C to F is independently selected from comonomer units having no reactive group, and copolymerizable with A and B, wherein Q.sub.1 to Q.sub.6 are reactive groups, and wherein the average total number (J) of Q.sub.1 to Q.sub.6 of the at least one polymer satisfies: 1.ltoreq.(J).ltoreq.4, the polymer having an ME of from 1,000 to 5,000,000. A resin composition containing the curable resin is also disclosed. The resin and resin composition of the present invention is advantageous in that both the resin and the resin composition not only have excellent durability and resistance to chemicals as well as excellent thermal and me…
