| Abstract: | The condensation of enzymatic hydrolysis lignin(EHL) with dimer acid(DA) was reported in this article.The influences of some factors on the yield and graft degree were investigated,including the type and concentration of the initiators,mass ratio of EHL and DA,temperature and condensation time.The structure of condensed polymer was characterized by FI-IR.According to the condensation efficiency,the optimum conditions for the condensation were as follows: initiator BPO(benzoyl peroxide)/CER(cation exchange r... |
