Abstract: | Butylmethacrylate(BMA) was grafted onto woolen fabrics by microwave Irradiation In the presence of catalyst ((NH4) 4S2O8) .Various parameters of graft- copolyme-rlzation reaction, namely time of reaction, microwave intensity, catalyst and monomer concentration, were optimized . The graft - copolymerization was also compared with conventional heating graft- copolymerization at the same condition, it showed microwave irradiation could Improve the reactivity of the monomer. The moisture regain decreased as graft add - on increased, the strength of the grafted fabric decreased as graft add - on increased , but the strain increased hi some degree. The infrared spectrum showed an additional peak at 1700 cm-1, confirming ester carbonyl groups of the monomer. |
