| Abstract: |
| The water-soluble chitosan prepared by acetylation was used to modify natural rubber latex（NRL），and the properties and structure of the modified NRL were investigated.The results showed that，the optimal pH value to dissolve water-soluble chitosan in water was less than 11.The surface of modified NRL film was smooth，and the film compactness and solvent resistance were better than those of unmodified NRL film.When the addition level of water-soluble chitosan was 1.5 phr，the optimum comprehensive physical properties of the NRL film were obtained.The modified NRL film possessed better biocompatibility，caused fewer allergies and had more application prospects in medical service domain. |
