| Abstract: | We successfully synthesized monomer casting polyamide 6 (MCPA6)/poly(methyl methacrylate) (PMMA) blends in two steps: (1) radical polymerization of methyl methacrylate in ?‐caprolactam and (2) anionic ring‐opening polymerization of this ?‐caprolactam solution. The influence of PMMA on the crystallization behavior of MCPA6 was studied with differential scanning calorimetry and X‐ray diffraction, which showed that PMMA could act as a heterogeneous nucleation agent and favored the formation of the γ‐crystalline form. The rheological properties were also studied and indicated that PMMA reduced the interaction between MCPA6 chains by lowering the density of hydrogen bonding. This study used a novel and convenient method to prepare microporous MCPA6/PMMA particles that involved removing the continuous phase. Their surface area and thermal stability were characterized by the Brunauer–Emmett–Teller method and thermogravimetric analysis, respectively. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2009 |
