Hydrophilic-hydrophobic two-component polymer networks: 2. Synthesis and characterization of poly(ethylene oxide)-linked-polybutadiene

摘要: Abstract Hydrophilic—hydrophobic two-component networks were prepared by reacting end-functionalized poly(ethylene oxides) with polybutadiene. The oxide)- linked -polybutadiene phase-separate even for very short polyether chain lengths. By transmission electron microscopy, a bicontinuous interpenetrating morphological structure was determined. Heat capacity analysis shows that the mobility of polybutadiene is influenced phase. same result obtained from stress—strain experiments. Analysis swelling data in different solvents (tetrahydrofuran, cyclohexane, water) show hydrophobic-hydrophilic balance such two—component altered varying crosslink density and
