摘要: Sequential poly(methyl acrylate)/poly(hydroxyethyl acrylate) interpenetrating polymer networks with different poly(hydroxyethyl contents were prepared by free radical polymerization of hydroxyethyl acrylate inside the previously polymerized network. Differential scanning calorimetry on dry samples shows that exhibit phase separation, and no differences are found between glass transition temperatures two phases present in network those pure components.
