A
polymerization
in which the growth of polymer
chains
proceeds by addition reactions between molecules of all
degrees of polymerization
.
Notes:
  1. The growth steps are expressed by: Px+PyPx+y{x}{1,2,};{y}{1,2,} where Px and Py denote chains of degrees of
    polymerization
    x and y, respectively.
  2. The earlier term 'addition
    polymerization
    ' embraced both the current concepts of 'polyaddition' and '
    chain polymerization
    ', but did not include '
    condensative chain polymerization
    '.
