天然橡胶-黄腐酸的非均相接枝聚合
摘要:
腐植酸是一种组份和结构很复杂的天然大分子[1,2]。利用腐植酸中的自由基进行烯类单体在腐植酸上的接枝聚合反应,已有报道[3,4,5],但尚未见到腐植酸与双烯聚合物反应获得接枝聚合物的报道。

HETEROGENEOUS RADICAL GRAFTING OF FULVIC ACID ONTO NATURAL RUBBER
Abstract:
At 60℃ and in the presence of benzoyl peroxide, fulvic acid has been grafted onto natural rubber through heterogeneous phase polymerization. Tbe grafted product is soluble in organic solvents in common with the original rubber. A new absorption band (1130 cm-1) appeared in the IR spectrum of the grafted polymer, indicating the presence of C-O-C bond as the grafting site. The Tg of the grafted polymer measured by DSC methed is -53℃.
