摘　　要：The self\|aggregation and gelation behaviors of atactic poly(methyl methacrylates)(aPMMA) in poly(ethylene glycol)(PEG) oligomers were studied by using FTIR spectroscopic measurements. The in\|situ variable temperature IR studies in aPMMA/PEG gel suggested that some aPMMA segments were in the aggregated state in solution, which became a node in the solution. With decreasing temperature, the fraction of aggregated aPMMA in solution increases, resulting in the gelation of aPMMA.The self\|aggregation and gelation behaviors of atactic poly(methyl methacrylates)(aPMMA) in poly(ethylene glycol)(PEG) oligomers were studied by using FTIR spectroscopic measurements.
