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.
For the condensation polymer
derived from the silsesquioxane monomer considered here, the mass m of the linear oligomer having n repeat groups is given in units of u by the equation:
As already noted, PLA is a condensation polymer
with lower molecular weight than PS, so it has intrinsically lower viscosity and melt strength.
Proaid 211 is a complex condensation polymer
of synthetic resins, glycerides and organic esters, designed as an internal lubricant and dispersant.
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.
Reactions 1-4 represent the breaking of a polyester inner bond caused by one of the functional groups, which may be present either as the chain ends of other macromolecules (of the same or of a different condensation polymer
), or in the structure of other reagents, such as, e.g., a reactive compatibilizer.
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.
