Conteúdo: |
Blends between poly(?-caprolactone) (PCL) and poly(methyl methacrylate-co-butyl methacrylate) (PMMA-co-BMA) were prepared by solution blending in the presence of dichloromethane as solvent. The compatibility of the blends was studied by FT-IR, Raman spectroscopy, micro-Raman imaging and thermogravimetric analysis. Cytotoxicity assays were also performed to assess the feasibility of using such materials in veterinary devices. Based on results, we conclude that PCL and PMMA-co-BMA form compatible blends owing to specific interactions between carbonyl groups of PMMA-coBMA and hydrogens present in the polymeric chain of PCL. Furthermore, these materials were not toxic to bovine fibroblasts, which supports their possible use in cattle veterinary devices. |
