This review highlights synthesis, catalytic properties of polymer-supported organic catalysts in the last 25 years, with emphasizing on some recent developments in the direction. The polymer-supported catalysts were first divided into achiral and chiral catalysts, and then divided into different sections according to the chemical reactions catalyzed. Some examples were included in order to make clear comparison based on the catalytic activity and selectivity. Some comparisons were made for achievability of separation and reuse of the supported catalysts. Different kinds of polymer supports were included, e.g. crosslinked polymers, soluble linear polymers and dendrimers. In this first part achiral organic catalysts were detailed.
