Abstract

The effect of pressures up to 4000 atm on the free‐radical cyclopolymerization of acrylic anhydride in solution has been investigated. Both the molecular weight and degre of cyclization of the polymer are increased by pressure. The rate of polymerization at first decreases with increasing pressure, but above 2500 atm a normal acceleration occurs.
