| 中文摘要 | the epsilon-caprolactam was used to block the isocyanate group to enhance the storage stability of allyl (3-isocyanate-4-tolyl) carbamate. the spectra of ftir and nmr showed that blocked allyl (3-isocyanate-4-tolyl) carbamate (btai) possesses two chemical functions, an 1-olefin double bond and a blocked isocyanate group. the ftir spectrum showed btai could regenerate isocyanate group at elevated temperature. dsc and tg/dta indicated the minimal dissociation temperature was about 135 degrees c and the maximal dissociation rate appeared at 226 degrees c. then the styrene-b-(ethylene-co-1-butene)-b-styrene triblock copolymer (sebs) was functionalized by btai via melt free radical grafting. the effect of temperature, monomer and initiator concentrations on the grafting degree and grafting efficiency was evaluated. the highest grafting degree was obtained at 200 degrees c. the grafting degree and grafting efficiency increased with the enhanced concentration of btai or initiator. |
