采用溴十二烷对硫酸盐木质素进行烷基化，以改善与聚丙烯（PP）的相容性。研究了PP/烷基化木质素复合材料的可行性。研究发现木质素可以作为PP基体的阻燃剂和增韧剂。此外，复合材料中较高的木质素部分表现出明显的阻尼效果。尽管扫描电子显微观察表明烷基化提高了 PP-木质素粘附力，但仅从冲击行为中获得了额外的好处。聚合物。 COMPOS., 32: 1019-1025, 2011。(C) 2011 年塑料工程师协会
The alkylation of kraft lignin with bromododecane was carried out to improve the compatibility with polypropylene (PP). The feasibility of PP/alkylated lignin composite was studied. It was found that the lignin could serve as fire retardant and toughening agent for PP matrix. Moreover, the higher lignin portion of the composites exhibited obvious damping effect. Although scanning electron micrographic observations indicated that PP-lignin adhesion was improved by the alkylation, additional benefits were only obtained from impact behavior. POLYM.
