    en.wikipedia.org/wiki/Merrifield_resin

    Merrifield Resin is a cross-linked polystyrene resin that carries a chloromethyl functional group. Merrifield resin is named after its inventor, Robert Bruce Merrifield (1984 winner of the Nobel Prize in Chemistry), and used in solid-phase synthesis. The material is typically available as white beads.

    There are many types of rigid cellular polystyrene (RCPS). The term "Styrofoam" is The Dow Chemical Company's brand name, which does not refer to any particular type of RCPS. Some polystyrene uses up to 50% recycled resin, including post-consumer plastic. Several states in the US have banned polystyrene that uses CFCs as blowing agents.

  7. Polystyrene sulfonate - Wikipedia

    en.wikipedia.org/wiki/Polystyrene_sulfonate

    Polystyrene sulfonic acid, the acid whose salts are the polystyrene sulfonates, has the idealized formula (CH 2 CHC 6 H 4 SO 3 H) n. The material is prepared by sulfonation of polystyrene: (CH 2 CHC 6 H 5) n + n SO 3 → (CH 2 CHC 6 H 4 SO 3 H) n. Several methods exist for this conversion, which can lead to varying degree of sulfonation.
