摘　　要：研究了用不同分子量的聚乙二醇(PEG)对呋喃树脂进行改性以改善其脆性较大的缺点.通过化学反应将具有柔性长链结构的聚乙二醇键接到呋喃树脂上从而增加了其韧性.研究结果表明,PEG分子量为400Da时,对呋喃树脂的增韧效果最好;其用量为25wt%时,呋喃树脂的断裂伸长率达到了5.51%,最大拉伸强度可达19.9MPa.Polyethylene glycol（PEG）s with different molecular weights were introduced into furan resin by chemical modification to overcome its large brittleness and the introduction of the flexible long chains of PEGs increased the toughness of furan resin.The results showed that PEG-400 had a better toughening effect when its quality content was 25wt%,the maximum tensile strength of the modified furan resin was 19.9 MPa with no significant decline and the corresponding breaking elongation was up to5.51%.
