METHOD FOR PRODUCING POLYMER COMPOUND

摘要

Provided is a method for conveniently and efficiently producing a polymer compound having a superior thickening effect, having as starting materials a plant that conventionally has been disposed of as waste, and having superior safety from the starting materials and a low environmental impact. The method for producing a polymer compound is characterized by obtaining a polymer compound from Corchorus capsularis L. and/or Corchorus aestuans L. and having a shear viscosity of at least 0.2 Pa∙s at a shear speed of 10 (1/s) and at 25°C of an aqueous solution having a concentration of 1 wt%, by means of the belowmentioned steps: step 1) alkali extraction; step 2) purification.
