Polymerization of Isobutylene with Gaseous BF3 at Low Temperatures in Bulk

Example 3.16 Cationic Polymerization of Isobutylene with Gaseous BF3 at Low Temperatures in Bulk 

Safety precautions Before this experiment is carried out, Sect. 2.2.5 must be read as well as the material safety data sheets (MSDS) for all chemicals and products used. 

Monomeric isobutylene is passed from a cylinder through a drying column filled with sohd potassium hydroxide pellets or lA zeolith and condensed in a dry cold trap. 10 ml of the condensate are collected in a dropping funnel installed directly below the trap.
