“…These materials have low viscosities in solutions and the molten state, good reactivity, are nontoxic and are soluble in polar solvents . Thus, HBPs have been modified with oil fatty acids isophorone diisocyanate,, succinic anhydride, polylactic acids, and MA to obtain materials with specific properties. However, there is little information on the functionalization of HBP with MA.…”
