Abstract

Methacrylic acid polymerized in the solid state leads to a much less syndiotactic polymer than when polymerized in the liquid state. This is taken as additional evidence for the importance of the geometry of the monomer crystal lattice in solid state polymerization. Butadiene‐1‐carboxylic acid polymerizes spontaneously in the solid state to a cross‐linked product, while the sodium, potassium, and barium salts of this acid are stable and polymerize very little, even on gamma‐ray irradiation.
