  1. Department of Forestry National Chung-Hsing University 2007 IUFRO All-Division 5 Conference Properties of the Polyblends Prepared from Polyhydric Alcohol Liquefied Japanese Cedar with Epoxy Resin Chiou-Chang Wu1 Wen-Jau Lee2 1Graduate student, Department of forestry, National Chung-Hsing University. 2Professor, Corresponding author, Department of Forestry, National Chung-Hsing University. No.250, Guoguang Rd., South District, Taichung City 402, Taiwan (R.O.C.)

  2. Fossil Renewable Sustainability Non-renewable Greenhouse Introduction Utilizing black liquid Biomass Nature resins modified Woody reactive Liquefcation

  3. Japanese cedar (Cryptomeria japonica) Liquefied products Liquefied agents (PEG400/glycerol; PEG600/glycerol) Liquefaction Solvent/wood: 3/1 w/w Catalyst: H2SO4 Reaction time: 75 min Temperature: 150℃ Experiment skeleton - LiquefiedJapanese cedar-

  4. epoxy resin Liquefied wood 0/100 40/100 Experiment skeleton - Liquefied wood/epoxy resin polyblends - Polyblending (LW/EP)

  5. Conclusions • DSC thermoanalysis of polyblends • It was an exothermic reaction. • It could be further cross-linked with heating. • LW/EP polyblends (60/100) vs.traditional epoxy resins -heating with 90℃ for 3 h -Its bonding strength was better.

  6. Appreciation for your comments
