Abstract: The self-aggregation and gelation behaviors of atactic poly(methyl methacrylates)(aPMMA) in poly(ethylene glycol)(PEG) oligomers were studied by using FTIRspectroscopic measurements. The in-situ variable temperature IRstudies in aPMMA/PEGgel suggested that some aPMMAsegments were in the aggregated state in solution, which became a node in the solution. With decreasing temperature, the fraction of aggregated aPMMAin solution increases, resulting in the gelation of aPMMA.

Key words: Atactic poly(methyl methacrylates), Selfaggregation, Gelation
