Synthesize M-DIPA Curing agent: |
|
| |
 |
| M-DIPA is an
excellent chain extender for Elstomeric polyrethanes (PU)
especially useful in systems Cured at room temperature.
It is also a curing agent for Epoxides (EP) and an intermediate
for organic syntheses. PU formulstions based on M-DIPA
are suitable ofr Castelastomers, RIM elastomers and coatings
for construction industry. In EP it is suitable for tooling,
prepregs, chemical resistant coatings, laminates and filamnet
winding. |

| Photochromism
of polymorphic 4,4 -methylenebis(N-salicylidene-2,6-diisopropylaniline)
crystals |
 |
| 4,4
-Methylenebis(N-salicylidene-2,6-dialkylaniline) derivatives
were prepared and their structures were determined by
1H NMR, IR, DSC and X-ray crystallographic analyses. The
2,6-diisopropylaniline derivative yielded definite polymorphic
crystals: the space groups of the crystals were C2/c and
P21/n, respectively. It was found that both polymorphs
were similarly photochromic but the thermal stability
of the photochrome was different due to the variance of
the shape of molecule and cavity in each crystal. |
