A final example of a stereoselective heterogeneous catalytic system is the work of Laycock, Collacott, Skelton and Tchir.17 Layered double hydroxide (LDH) synthetic hydrotalcite materials were used to stereospecifically polymerize propylene oxide [PO] to crystalline isotactic and liquid atactic poly(propyleneoxide) [PPO]. These authors suggest that the LDH surface acts as other inorganic or organometallic coordination initiators or catalysts by providing specific surface orientations for propylene oxide monomer. X-ray powder diffraction showed some loss of crystallinity after calcination and X-ray photoelectron spectroscopy showed an enhancement of Mg/Al content due to restructuring of the Mg and A1 surface atoms. The surface was also rich in Cl ... 

Layered silicate clays intercalated by pillaring poly-oxocations are precursors to an important class of mi-croporous catalysts. Smectite clay was the only host structure known to be pillarable by purely inorganic oxo ions. Recently, layered double hydroxides (LDH) pillaring oxo ions were reported by Pinnavaia and coworkers [79, 80]. 

For PNCs, the layered double hydroxides (LDHs) constitute a new class of mainly synthetic, reinforcing nanoparticles. During synthesis, LDHs may be preintercalated with organic anions. Unfortunately, most LDH platelets are thin, f=0.6 0.1nm, small in diameter, d=30 to 40 nm [Wu et al., 2007]), and decompose thermally at T IOTC [Camino et al., 2001]) consequently, their main application has been for absorption of HCl during dehydrochlorination of poly(vinyl chloride) (PVC) and halogenated polymers, or as flame retardants. The flow behavior of polyethylene (PE) with LDHs was reported to be similar to that of CPNCs [Costa et al., 2006]. There are no commercial PNCs with LDHs on the market, but experimental products such as Perkalite, a preintercalated aluminum-magnesium (Al-Mg) LDH, have been...

Under microwave irradiation, in situ polymerization constitutes an alternative method for preparing poly(ethylene terephthalate) (PET)/layered double hydroxide (LDH) nanocomposites. LDHs are also known as anionic clays or hydrotalcite-like compounds. To overcome the lack of compatibility between PET and LDHs that contain purely inorganic anions, LDHs were modified with dodecyl sulfate prior to sample preparation. The preparation time was considerably reduced, and the inorganic filler was well dispersed and exfoliated in the polymer matrix. The nanocomposites thus obtained were thermally more stable than original PET,...
