This work is relative to attempts for obtaining acid-thiol supported polymers that may be used as solid bifunctional catalysts, active in the Bisphenol A synthesis. Five approaches are tested with modified sulphonic styrene-based polymers obtained ei

To improve and extend the properties of organic polymer-supported cata- lysts, the corresponding functional polymers were grafted on porous silica. Mechanical stability and constant shape, which are independent of solvent nature, and the possibil- it

Possibilities for enhancement of catalytic reaction rate by combining adsorptive (unfunctionalized) and catalytically active (functionalized) domains within the polymer skeleton of ion-exchanger catalysts have been studied. These catalysts were prepa

The synthesis and characterization of polyisoprene bearing carboxylatobetaines of various intercharge lengths, either at one or at both ends of the polymer chain, are described. Peculiar properties such as associative behaviour may be expected due to

The influence of several phosphorus(III) ligands upon the activity and the stereoregulation ability of the soluble organometallic complex [Ni(η3-(2-methylallyl))(η4-COD)]PF6 (COD = 1,5-cyclooctadiene), 1, is studied. There is a general increase of

Silanes are versatile coupling agents. They represent an easy way of chemically bonding polymers to silica. Two processes have been considered: polymerization from a coupling agent grafted on the surface; and reaction of a prefunctionalized polymer b

A large number of styrene-divinylbenzene copolymers (St-DVB) were synthesized using 2,2,4-trimethylpentane as pore-forming agent. Diluent and crosslinking agent (DVB) contents were varied in the ranges 20–60 vol.-% and 2–40 vol.-%, respectively,

Size Exclusion Chromatography (SEC) is a convenient and powerful method for polymer characterization, but alternatives have appeared to overcome its limitations or improve its responses. These methods are examined, comparing their advantages and disa

The ladder polymer, polyphenylsilsesquioxane, has been grafted onto porous silica and sulfonated to obtain catalysts of high stability with enhanced site accessibility and increased number of sites, as well as high acidity level. The catalytic behavi
