摘要
本文详细研究了(?)丁内酯与活性聚丁二烯锂的反应机理和产物:探讨了高活性种浓度下影响聚丁二烯微观结构的因素;用萘-锂络合物作为引发剂,在抽余油中合成了高乙烯基含量,多官能度的丁羟胶。
This paper studied the reaction mechanism and product between γ-butyrolactone and polybutadienyl-Li. investigated the factors affecting the microstructure of polybutadiene on this condition. By using γ-butyrolactonc as terminater, naphthalene- Lithium as initiator, extract oil as solvent, a hydroxyl terminated polybutadienc with poly-hydroxyl and high vinyl contents has been obtained.
