Results show that the LCST
also increased proportionally to the polymer concentration.
If one of each of these two different LCST
copolymers is conjugated to a different antibody, then two different analytes may be assayed in the same serum sample by raising the temperature of the system to sequentially phase-separate the two different polymer-conjugated immune complex sandwiches (Fig.
Blends of polyisoprene with polybutadienes of intermediate vinyl contents (24-35%, depending on polymer molecular weight) exhibit LCST
0 and heated to various temperatures to determine the range of the LCST
The initial basic LCST
device is designed to work with one-way and two-way cable systems.
and the swelling properties of the gels were investigated.
When the water of 25[degrees]C (below the LCST
of PNIPAAm) was used as the coagulant, the phase-separation process is dominated by instantaneous liquid--liquid demixing.
Furthermore, they also found that the LCST
can be reduced progressively increasing the molecular weight of the heat-sensitive segments or adding salt to the solution; the latter effect is known as "salting-out effect.
It was found that the enzymatic degradation of all the hydrogels was significantly inhibited below the lower LCST
and above the higher LCST
because of the steric hindrance of the graft chain (below the lower LCST
) and shrinking of the poly (NIPAAm) copolymer crosslinker (above the higher LCST
For example, the LCST
of poly(NIPAAm) (PNIPAAm) homopolymer aqueous solution is about 32[degrees]C, close to the human body temperature (7), and can be easily manipulated buy copolymerization with other monomers (8).
The cross-linked structure of PNIPA has characteristics of hydrogels, which exhibit a critical gel transition temperature (CGTT) instead of LCST
Hyperbranched/epoxy blends showed  complex phase diagrams with UCST behavior (Upper Critical Solution Temperature) at high temperatures and LCST
(Lower Critical Solution Temperature) behavior at low temperatures.
