| Sumario: | The objectives of this research determine for optimum condition modification with effect of 3-(trimethoxysilyl) propyl methacrylate on physical properties of Poplar wood-polymer were performed. Test samples from Poplar species were divided to five levels: control, Acidified Ethanol/Silan/110 ˚C, Acidified Ethanol/Silan/150 ˚C, Ethanol / Silan / 150°C and Silan/150°C in two levels with and without Benzoyl peroxide. Samples were impregnated with silan compound according to vacuum-pressure method in experimental cylinder. Weight percent gain of Silan/Et/BP/150 ˚C level by 24/40% had the maximum value were determined. Bulking efficiency and OH groups substituted in Silan/AEt/150 level with 6.81 % and 1.10 mol/gr, respectively compared with the other levels.Modification were resulted to improve water absorption and dimensional stability that maximum dimensional stability in contain initiator level were determined. In immersion-dry period test, the highest and lowest bulking efficiency in Silan/AEt/150 and Silan/Et/150 were reported. Maximum of weight loss in immersion-dry test was determined in Silan/AEt/110 with the 3.6% value.Key words: physical properties, 3-(trimethoxysilyl) propyl methacrylate, Asidified Ethanol, bulking efficiency |
