Abstract
Statistical parameters for the postgel stage of an ideal A2 polycyclot rimerization were derived and compared with the corresponding paramete rs for an A3 homopolymerization. Both gel fraction and crosslink densi ty increase less with conversion for the former case. This is due to t he fact that branching units are present at a constant concentration f rom the beginning of the A3 homopolymerization, but show a linear incr ease with conversion, from zero to the maximum value, for the A2 polyc yclotrimarization.
