AbstractA crosslinked polymer based on α‐pinene and furfural suitable for processing into ion exchangers was prepared. The polymer has been processed chemically into different types of cation exchange resins. The role of various parameters such as catalyst concentration, proportion of crosslinking agent, etc., for preparing the polymer is systematically studied and presented. Similarly, the conditions for preparing the various cation exchange resins (sulfonic, phosphonic, and hydroxy phosphonic acid type from the polymer) are also described. A probable/possible composition for the repeating unit in the basic polymer is proposed and supported by experimental evidenc
