Title: Sugar Cane Bagasse Lignin As A Stabilizer For Rubbers: Part Ii-butadiene Rubber
Author: De Paoli M.-A.
Furlan L.T.
Abstract: In this work we have studied the stabilizing effect of the lignin, obtained as a by-product of the acid hydrolysis of sugar cane bagasse, herein called sugar cane bagasse lignin, on the thermal and environmental degradation of butadiene rubber. This stabilizer was investigated in various concentrations in the pure form and as a substitute for a hindered phenol, in a commercially used formulation also containing a p-phenylene-diamine. For thermal degradation the stabilization level of the commercial sample is reached with 1·3% of pure lignin and the substitution of the hindered phenol in the commercial formulation increased the stabilization by a factor of 1·2. In the environmental ageing experiments the performance of the rubber stabilized with lignin was poorer than that of the commercial sample. This behaviour is assigned to the strong degradative effect of light on the rubber. © 1985.
