An important event in the science of polymer chemistry has been announced recently by the DuPont Company, which announced a new process for making polymers by what is called group transfer polymerization (GTP). Interestingly enough, this important scientific advance has practical ramifications in the area of automotive coatings. There are today three important ways to make polymers. The first is by initiation of the polymerization with free radicals. The second is by initiation with ions, either cations or anions. The third method is by use of the well‐known Ziegler‐Natta catalysis. It is by this latter technique that high density polyethylene, polypropylene, linear low density polyethylene and a number of other important polymers are made.
