I put together a small Python notebook that fits copolymer reactivity ratios (Fineman–Ross or Kelen–Tudos) and predicts Tg with the Fox equation to speed up synthesis planning. Used it last week to target a 60/40 MMA/BA with Tg about 30 °C and hit 32 °C at 78% conversion — happy to share the template and would love pointers to similar open tools (especially for RAFT kinetics).
