Abstract: Disclosed  herein is an acrylamide polymer characterized by molecular weight in the range of 2000-5000 Da, the particle size of 80 to 200 nm,  the zeta potential value of the polymer being in the range of -15.78 meV to -25 meV. The developed multifunctional syntan is  synthesized from a non-toxic biocompatible monomer. The polymer of the invention finds enormous application in leather processing  industry as a synthetic tanning agent. It finds application in various stages of leather processing such as pretanning, rechroming, and  post tanning, essentially as a filling agent as well as the chromium exhaustion aid. Further, the invention finds application in the  leather industry as a replacement for formaldehyde and acrylic acid free phenolic and acrylic syntans. The invention also provides a  process for the preparation of the said multifunctional polymer.
