对聚异丁烯苯酚的合成及表征

Synthesis and characterization of P-polyisobutylene phenol

以高活性聚异丁烯（PIB）和苯酚（C6H50H）为原料，三氟化硼乙醚-三氧化二铝（BF3 ·C4H10O-Al2O3）为复合催化剂合成了对聚异丁烯苯酚。并通过傅立叶变换红外光谱（FT-IR）和超导核磁共振光谱（NMR）对合成的对聚异丁烯苯酚进行了研究，结果表明此法合成的对聚异丁烯苯酚具有很高的选择性，产物中不含其它异构体。采用差示扫描热分析（DSC）对合成的对聚异丁烯苯酚的进行分析，结果表明对聚异丁烯苯酚与高活性聚异丁烯相比，具有较高的热稳定性。

Synthesis of P-polyisobutylene phenol by alkylation of phenol （C6H5OH） with high active polyisobutylene （PIB） in the presence of BFyC4H10O-Al2O3 as complex catalysts. The P- polyisobutylene Phenol was investigated by the fourier transform infrared spectroscope （FT-IR） and the nuclear magnetic resonance （NMR）, the results showed that there was remarkable choice of the P- polyisobutylene phenol and there were no other isomers. The P-polyisobutylene Phenol was analyzed by differential scanning calorimetry （DSC）, the result showed that the heat stability of The P- polyisobutylene Phenol was higher than the high active polyisobutylene.
