It is now IS years since the first patents in polymer supported
metal complex catalysts were taken out. In the early days
ion-exchange resins were used to support ionic metal complexes.
Soon covalent links were developed, and after an initially slow
start there was a period of explosive growth in the mid to late
1970s during which virtually every homogeneous metal complex
catalyst ever reported was also studied bound to a support. Both
polymers and inorganic oxides were studied as supports, although
the great preponderance of workers studied polymeric supports, and
of these polystyrene was by far the commonest used. This period
served to show that by very careful design polymer-supported metal
complex catalysts could have specific advantages over homogeneous
metal complex catalysts. However the subject was a complicated one.
Merely immobilising a successful metal complex catalyst to a
functionalised support rarely yielded other than an inferior
version of the catalyst. Amongst the many discouraging results of
the 1970s, there were more than enough results that were
sufficiently encouraging to demonstrate that, by careful design,
supported metal complex catalysts could be prepared in which both
the metal complex and the support combined together to produce an
active catalyst which, due to the combination of support and
complex, had advantages of activity, selectivity and specificity
not found in homogeneous catalysts. Thus a new generation of
catalysts was being developed.
