Gelator In Situ Modify PMMA

Abstract:

Gelator (G₂-C₁₂-G₂) was synthesized successfully, the structure of which was confirmed by ¹H-NMR and Mass spectra (MS). And G₂-C₁₂-G₂ was used to modify PMMA by “in-situ” polymerization. The results of gel permeation chromatography (GPC) showed that Mn and M_w/M_n of the PMMA composite were barely influenced by the incorporation of gel. The results of dynamic mechanical analysis (DMA) showed that the modified PMMA had higher modulus, toughness and glass transition temperature (T_g) than pure PMMA. Furthermore the results of spectrophotometer showed that the transparency of modified PMMA was nearly the same as pure PMMA .
