Polymer Networks: Principles of Their Formation, Structure and Properties
Springer, 1998 - Science - 343 pages
Written by an international team of authors with a strong emphasis on the underlying chemistry, this book forms a timely, concise, and accessible evaluation of the fundamentals of polymer network formation, structure, and properties, and how these three aspects are interrelated.

With only difunctional reactants, linear polymers are formed. Thus, hydrated
formaldehyde (HO-CH2-OH) has effectively two reactive -OH groups, phenol is
effectively trifunctional as the hydrogens in the ortho and para positions to the
K is the ratio of the rate constants for the reactions RA2 + R'B2 and RA2 + R"C3.
trifunctional (/ = 3) RIM systems . When the reactivity of the soft- segment
prepolymer is high (K = 1000 or 100), the prepolymer is consumed during the
The calculations are based on the idealized structure of an (AB)„-segmented
copolymer shown in Figure 5.11, for which Ns is determined from two arms of the
trifunctional polyether soft segment, and the value of NH is determined from a ...
