PURPOSE:To obtain the titled thermoreversible crosslinkable polymer compound, by radical-copolymerizing N-acryl-piperidine with N-methylolacrylamide in a solution state. CONSTITUTION:A mixture of 1mol of N-acrylpiperidine of formula I and 2mol or below N-methylacrylamide of formula II is dissolved in a solvent (e.g., methanol) so that the concentration of the formed solution may be 1-100%. This solution is copolymerized at 100-200 deg.C for 1-500min to obtain a crosslinkable thermoreversible polymer compound comprising units of formula III and 0.1-66mol% units of formula IV and having, preferably, an intrinsic viscosity [eta]as measured in a chloroform solution or a methanol solution at 30 deg.C of 0.01-6.0. This polymer compound has a property of being easily crosslinked when its molding is heated, so that it can be used as a mechanochemical material, a light-screening material or an adsorbent or for toys, separation membranes, etc. |
