Novel network polymer films were prepared from glutamic acid diethylester hydroehloride (2Et~Glu.HC1) and hexamethylene diisocyanate (film A) or lysine triisocyanate (film B). Prepolymers prepared by melt polyaddition were cast from dimethylformamide solution and then post-polymerized at 240 Β° for v
Addition reaction of (3-methyl-3-oxetanyl)methyl acetate (MOMA) with bis(4-mercaptophenyl) sulfide (BMPS) was examined in certain organic solvents. When the reaction of MOMA with BMPS was performed without any catalyst in hexamethylphosphoric triamide (HMPA) and N-methyl-2-pyrrolidone (NMP) at 130Β°C
