Natural rubber grafted with poly(methyl methacrylate)
(NR-g-PMMA) was prepared with a NR/MMA ratio of 90/10
by weight, and subsequently epoxidized in its latex state
via in situ performic acid to create materials with epoxide
contents of 10, 20 and 30 mol%. The grafting efficiency
was 94.3% and the grafted PMMA content remained more
or less unchanged after epoxidation.
