| Abstract: | The emulsion graft polymerization of butylacrylate (BA ) and degraded natural rubber latex (DNR) initiated by five model redox initiation systems were studied .Effects of initiator concentration various amount of oxidative agent,reductive agent and emulsifying agent on the monomer conversions and graft ratio of the sample are discussed。 The experiment results show that tertiary butyl hydroperoxide (TBPO)-tetra ethylene pentamine (TEPA) redox initiation system is the most appropriate for the preparation of butylacrytate and degraded natural rubber latex polymers。 |
