Polyacrylamide is a condensation polymer
which has very useful properties.
dagger]) This type of crosslinking is well known in condensation polymer
systems, but not so well known in acrylic or styrene-acrylic addition polymers used in the coatings industry.
Proaid 211 is a complex condensation polymer
of synthetic resins, glycerides and organic esters, designed as an internal lubricant and dispersant.
Examples of this usefulness are described for a simple linear homopolymer to demonstrate the method fundamentals, a condensation polymer
to demonstrate its utility in understanding complex spectra with multiple repeating patterns on different mass scales, and a condensation copolymer to demonstrate how it can elegantly and efficiently reveal unexpected phenomena.
As already noted, PLA is a condensation polymer
with lower molecular weight than PS, so it has intrinsically lower viscosity and melt strength.
Because it is a condensation polymer
, presence of even a very small amount of moisture during melt processing causes degradation of polymer chains and loss of molecular weight and mechanical properties.
Additional applications include analysis of condensation polymer
systems, (2) alkyd and polyester resins, silicone polyesters, polyurethanes, epoxy resins, polysiloxanes, polyamides, vinyl polyesters, phenol formaldehyde resins, rosin derivatives, and cellulosics derivatives.
These reactants may include a monomer and a catalyst, two reactants of a condensation polymer
, or a fusible polymer with a chemical heater.
In contrast, condensation polymers
are formed by a stepwise reaction of molecules with different functional groups.
In addition, maleic anhydride depolymerizes condensation polymers
such as PET and PC, thus obviating its use in mixed streams such as PCR containing olefins, PET, and other assorted polymers.
Interchange reactions involving condensation polymers
such as polyesters and polyamides have been reviewed by Kotliar in detail .
