  子量分佈在 1.3 左右，同時也探討了溫度效應、溶劑效應、起始劑濃度及共起始劑（co-initiator）
  對液態聚丁二烯微細構造（microstructure）之影響，作系統化的研究。(
• 英文摘要： Liquid rubber became a product with thehighest potential in the rubber industry, becauseof its easy processing ability. Anionic poly-merization was the best way to synthesize liquidrubber since it had many merits in variousaspects. In this paper, carboxyl terminatedpolybutadiene and hydroxyl terminated polybut-adiene were synthesized by living anionic poly-merization technique with lithium naphthaleneas the initiator. The molecular weight of theproduct could be controlled freely under 6,000.In some cases, the molecular weight could evenbe lowered to 1,000. The ratio wasaround 1.3. Systematic studies of the effects oftemperature, solvent, initiator concentratian andco-initiator on the microstructure of liquid poly-butadiene were also carried out.
