Abstract:

The new process for producing hydrolytic polymaleic anhydride (HPMA)was studied.Water was used as solvent in this process,27.5% of H₂O₂ as the initiator and cat. C as the specific polymerization catalyst.It can produce high quality HPMA,based on GB10535-89.having a long storage life and a low content of unsaturated monomer. This product has remarkable economical and environmental benefits.
