Polystyrenes incorporation

The surfactants only slightly affect polystyrene incorporation up to the surfactant concentration where surfactant adsorption on the particles is maximal,54,76 that is 0.02 mol kg 1. At higher surfactant concentrations the amount of free surfactant that is surfactants not adsorbed on the particles... [Pg.495]

The continuous decrease in A1203 incorporation in copper is also explained by a change in particle surface composition.43 Chloride present as an impurity forms CuCl, which adsorbs on the particles and thereby inhibits the adsorption of copper ions on the particles. This is an effect characteristic for a copper sulfate bath and was not found in nickel or cobalt baths. A different type of aging was reported for the codeposition of aggregated polystyrene particles with zinc.54,76 Polystyrene incorporation increased continuously in successive experiments, where the rotation speed of a cylinder electrode was randomly varied. Thixotropic viscous behavior of the aggregated suspension causes changes in aggregate size and suspension viscosity with rotation speed of the same time-scale as the experiments. [Pg.498]

Cross-linked polystyrenes, incorporating pendant ethyienediamine units, have been previously described [4,12,1,3], They are a poor choice for one-step functionalization supports, as alkylation with 2-substituted 4-chlo-romethylphenol.s doe.s not proceed to completion [14], and the unreacted -HN- CH, CH, NH units are strong metal-ligating sites [15], interfering with the metal complexa-tion of the main ligand.

A basic requirement for metal complexes to function as catalysts is the availability of an open coordination site and the isolation of the metal complex on the polymeric matrix. This is only achieved when the polymer is rigid. Thus, when (mesotetraphenylporphyrin) iron [Fe TPR] was reacted with 2% cross-linked polystyrene incorporating imidazole, a six-coordinated diamagnetic complex with two resin-bound imidazoles (Fig. 14-2a) was formed (Collman and Reed, 1973). In subsequent experiments, a paramagnetic, five-coordinated Co >TPP (Fig. 14-2b) was also prepared (Collman et al., 1974) by using a 20% cross-linked resin. [Pg.228]
