Monomer cast (MC) nylon was prepared by anionic ring-opening polymerization in the presence of sodium hydroxide catalyst and toluene-2, 4-diisocyanate cocatalyst under normal pressure.

It should be emphasized that the amount of cocatalyst used in this study is much smaller than in the reported studies.
Metallocene and post-metallocene catalysts are both used with MAO cocatalyst or other boron-based activators like borates.
Our aim was to prepare PE-MWCNT nanocomposites by a suitable method and to study the mechanical properties of the obtained nanocomposite using the metallocene ([Cp.sub.2]Zr[Cl.sub.2])-catalyzed olefin polymerization in combination with MAO cocatalyst. Recently, we reported a one-pot method, using metallocene catalysts, to control PEMWCNT nanocomposite morphology by the sonication method [20].
Also, the enhanced light absorption and scattering, as well as the flexibility to play either as electron donor or electron acceptor depending on the needs, make Bi nanostructures a sound choice as cocatalyst in Bi/semiconductor hybrid systems.
This is important since certain types of either "acidic" or "alkaline" species (typically byproducts of the resin polymerization catalyst and cocatalyst) can promote discoloration of certain types of phenolics by accelerating the oxidation process.

Polyurethane foam with CPP was prepared by mixing approximately 100 wt% polyether polyol, 1wt% surfactant, 0.4 wt% catalyst, 0.4 wt% cocatalyst, and 2.5 wt% water at the beginning forming the premixture.
[Al.sub.2][O.sub.3] was a cocatalyst in each experiment but was limited to 0.1 g (0.0002 lbs) as a cocatalyst in these experiments as opposed to its usual 0.5 g (0.001 lbs).

For this reason, a different strategy based on the use of cocatalyst able to enhance the activity for the [O.sub.2] evolution maintaining the photo-activity constant can be useful.
