Hydrophilic-hydrophobic two-component polymer networks: 1. Synthesis of reactive poly(ethylene oxide) telechelics

摘要: Abstract 1,2,4-Triazoline-3,5-dione groups are attached to the ends of poly(ethylene oxides) different chain lengths in a sequence polymer analogous reactions. The 1,2,4-triazoline-3,5-dione group is highly reactive functional for Diels-Alder and ‘ene’ reactions at room temperature quantitative yield. functionality telechelics 1.9–2.0. hydrophilic oxide) chains with α,ω-1,2,4-triazoline-3,5-dione can be used crosslink hydrophobic polymers like polybutadiene obtain oxide)-linked-polybutadiene two-component networks.
