Campbell D.S., . and Farley P. S., . Acid-catalysed hydrolysis of epoxidised natural rubber: gel formation during latex epoxidation. pp. 242-254. ISSN 0127-7065
Abstract
The accumulation of a gel phase in the bulk products of epoxidation of polyisoprene latices is shown to be strongly dependent on both the proton acidity of the epoxidation medium and on the extent of epoxidation within the particles of the latex. Comparison of the degree of swelling of the gel phase in a hydrocarbon solvent and in a solvent which is capable of acting as a hydrogen bond acceptor demonstrates that the gelation is largely the result of secondary interactions between polymer chains and that the incursion of permanent inter-chain ether links must be minimal under the usual conditions of preparation of epoxidised natural rubber.
