The results showed that Japanese cedar, Ma bamboo and Makino bamboo all had a good liquefaction efficiency as liquefied in polyethylene glycol/glycerol co-solvent with H2SO4 as a catalyst. The properties of PU foams made from liquefied woody material were influenced by the formulas of PU resins. Wherein, the PU foams made with a higher ratio of isocyanate would had a more complete crosslinking structure, a better mechanical properties and solvent resistance, and a lower water adsorption.

由试验结果得知，以PEG-400/glycerol为液化药剂，H2SO4为催化剂对柳杉、麻竹及桂竹均有良好之液化效果；液化木质材料所制造PU发泡体之性质受各成分调配比例所影响，其中异氰酸酯比例较高者，其PU树脂中液化木质材料之架桥反应较完全，发泡体机械性能及耐溶剂性较高，吸水性较低。

In this study, Japanese cedar, Ma bamboo and Makino bamboo were liquefied in polyethylene glycol/glycerol co-solvent with H2SO4 or HCl as catalyst. The liquefied woody materials were blended with PMDI (4,4'-Diphenylmethane diisocyanate;MDI) to prepare the PU foams. The effects of preparation conditions of PU resin on the properties of PU foams were investigated.

中文摘要本研究将柳杉(Cryptomeria japonica； Japanese cedar)、麻竹(Dendrocalamus latiflorus； Ma bamboo)及桂竹(Phyllostachys makinoi； Makino bamboo)等木质材料以聚乙二醇及丙三醇之混合液为溶剂，H2SO4及HCl为催化剂进行液化处理，并将其液化木质材料与4，4'-二苯甲烷二异氰酸酯反应制造聚胺基甲酸酯发泡体，探讨PU树脂调配条件对PU发泡体性质之影响。

The initiator B for high-pressure polyethylene production, imported byPetroleum Chemicals Factory of Lanchow , after storage under 15°C. overa period of ten years, gave poor results when used in production.

兰州石油化工厂过去从国外进口的高压巨乙烯引发剂B经过在15℃以下冷库中贮放十年以上时间，用于生产效果不好，我们对其原因进行了分析研究。
