Graft Modification of Collagen with Acrylonitrile in Concentrated Zinc Chloride Aqueous Solution

Abstract:

Graft modification is a common means to improve performance of natural polymers. Graft modification of collagen with acrylonitrile in zinc chloride aqueous solution was developed to apply in improvement moisture absorption of synthetic fiber. Polymerization yield, graft ratio and graft efficiency increase at first and then decline following monomer concentration, they reach the top when monomer concentration is 7.0 wt%. Graft ratio and graft efficiency increase at first and then decline following initiator concentration, they reach the top when initiator concentration is 0.2 wt%. Polymerization yield consistently rises with the increasing initiator concentration. Polymerization yield, graft ratio and graft efficiency drop with the increasing collagen concentration. The optimal reaction conditions are: reaction time , 90min; reaction temperature, 60°C; monomer concentration, 7.0 wt%; initiator concentration, 0.2 wt%.
