| Abstract: |
| The effect of the lignin powder modified by acetone on the reinforcement to BIIR was investigated. The test results showed that the viscosity of hydroxymethylated lignin water suspension was significantly decreased，the aggregate size of dry hydroxymethylated lignin was remarkably reduced promoting the powdering process of lignin and the recovery was decreased very little by modifying the lignin with acetone. It was found through the comparison for physical properties of the vulcanizates that the reinforcement of hydroxymethylated lignin was significantly increased by the modification with acetone. |
