Using the method of latex polymerization,poly vinyl acetate was synhesized with PVA as protective colloid,which was crosslinked with formylamine-group containing component.
From rosin purified abietic acid was prepared by using abietic acid as stared material acylamino surfactant was synthesized by maleric anhydride and diethanolamine.
The synthsis methods of N-sulfuryl substitude hetercycles by the reaction of alkyne with sulfamide catalyzed by diverse transition mentals were reviewed in this paper.
