Abstract
Provided is a polymer having a sharp melting peak and allowing easy adjustment of the melting peak temperature. Specifically provided is a polymer having two or more kinds of constitutional units containing an alkyl group having 14 or more and 30 or less carbon atoms, wherein the proportions of the number of the two or more kinds of constitutional units containing an alkyl group having 14 or more and 30 or less carbon atoms are each 20% or more, with respect to 100% of the total number of all constitutional units containing an alkyl group having 14 or more and 30 or less carbon atoms. An enthalpy of fusion of the polymer observed within a temperature range of 10° C. or higher and lower than 60° C. in differential scanning calorimetry is 30 J/g or more.
