Synopsis
The change of the properties of lignocellulose-polymethyl methacrylate composites with the polymer load is affected by the glass to lignocellulose ratio. In general, there is a limit, i.e., maximum or minimum, for the change of the properties with the change of the glass to lignocellulose ratio. The lignocellulose substrate has been found to affect the composite properties. Ball-milling of the substrate deteriorates the properties. Composites prepared with the use of sodium bisulfite-soda lime glass system as initiator showed, in general, improved properties, compared with ceric ammonium sulfate. The reverse was achieved on prehydrolysing the substrate. Prehydrolysis leads to composites of inferior properties, in general. Alkaline pre-treatment of bagasse ground or semichemical pulp, depressed the compression strength. The other properties improved for composites from bagasse semichemical pulp, while improved or deteriorated for samples from ground bagasse, depending on the kind and con-centration of the alkali used in pre-treatment, also, on the particle size of the ground bagasse. Subsequent mechanical treatment of alkaline treated unground bagasse resulted in improved properties, compared to those due to mechanical nontreatment of the ground one.
