High tensile strength retention of the modified rubber latex films on ageing were shown to be attainable by addition of appropriate lignin related compounds in the modification reaction. Molecular weight and gel content determination indicated that the simultaneous effect of rubber degradation as a side effect of modification was negligible in the batches comprising ferulic acid and coumaric acid. The viability of the modified rubber in the use as technological rubber latex products which requires higher resistance to oxidative ageing was assessed. back
