- Polyaddition
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+Py → Px+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'. (en)
