Abstract
Hydrogenation of neoprene (CR) latex was carried out by utilization of diimide with
boric acid as a catalyst. Various hydrogenation conditions were studied and the hydrogenation
degree could reach 48.1%. The most effective ratio of hydrogen peroxide/hydrazine hydrate was 0.8.
The hydrogenation degree increased with increasing the temperature, the amount of boric acid and
hydrazine hydrate. However, it decreased as prolonging the reaction time. The gel content was also
investigated. Microstructure of hydrogenated neoprene (HCR) was characterized by IR and
1HNMR.
