摘要
One new hydroxypropyl hydroxyethyl starch derivative with fine thermoplasticity,of which glass temperature T g≈140℃ and flow temperature T f≈170℃,was prepared when corn starch was properly coupled with epichlorohydrin then hydroxypropylated and hydroxyethylated in high substitution values.The derivative might be able to used alone or as an additive to plasticate with plastics etc for degradable materials.
