Abstract
The present invention provides a polymer which has a polymerizable functional group but still can be thermoformed without being crosslinked and which undergoes crosslinking upon irradiation with an active energy ray after being formed, and a composition including the polymer. An active energy ray crosslinkable thermoplastic polymer includes specific monomer units (1). The ratio of the number of moles of the monomer units represented by the general formula (1) to the number of moles of all monomer units constituting the polymer is not less than 1 mol %. The number average molecular weight (Mn) of the active energy ray crosslinkable thermoplastic polymer is 20,000 to 500,000.
