Polyaddition

Source: Wikipedia, the free encyclopedia.
IUPAC definition

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'.[1]

Polyaddition (or addition polymerisation

polycondensation and in contrast to chain polymerization.[4]

A typical polyaddition is the formation of a polyurethane.
