Order-Disorder Tricriticality in ${\mathrm{A}}_n{\mathrm{B}}_n$ Star Polymer Melts

Minhoon Kim, Wonjun Kang, Daeseong Yong +2

Tricriticality usually requires tuning an additional thermodynamic parameter. Here we show that, in symmetric ${\mathrm{A}}_n{\mathrm{B}}_n$ star-polymer melts, the arm number $n$ itse…
