Responsive functionalized polymers have as of late discovered across the board applications as receptive materials in an assortment of biological and other mechanical uses in light of the benefits of the useful gathering and the properties of the polymer atom The utilization of receptive polymers in strong stage union has additionally developed as an appealing methodology after Merrifield's progressive creation of the strong stage peptide blend. Functionalized polymers were utilized as particle trade media far ahead of schedule in the mid 30's, however their orderly utilize began just later in after the presentation of strong stage amalgamation by Merrifield. Polymeric reagents are responsive functionalized polymers which are utilized to impact the synthetic changes of a receptive substrate to manage the cost of the item in which the depleted reagent is effortlessly evacuated & the response medium and it can be regenerated. Such functionalized polymers have numerous applications as particle exchangers. The main aim of using the modified polymer transition metal complexes as catalysts is because of their high reactive nature and the finds tremendous applications in the industries
