ABSTRACT:
Certain linear alternating polymers of carbon monoxide and styrene are characterized by a high degree of syndiotactic character. This degree of syndiotactic character is reduced together with an attendant increase in atactic character by contacting the syndiotactic polymer with organ base at an elevated temperature.
