摘　　要：　用红外光谱、紫外光谱、差示扫描量热等手段表征了掺杂体系内钛螯合物(Ti Ac)与丙烯酸酯共聚物的相互作用。测试了Ti Ac用量对涂膜耐水性、耐热性及复溶性的影响。结果表明,当wTi Ac=0.015时涂膜的吸水率可下降到1%以下,且涂膜仍保持较好的复溶性(15s)。IR, UV and DSC analyses were used to characterize the interaction of the acrylate copolymers with the titanium chelate(Ti-Ac). The effect of the chelate amount on the water resistance, heat stability and film resolubility of the copolymer film were studied. When the chelate was added (w_(Ti-Ac)=0.015), the water uptake of the resulting film was lowered to less than 1%, and the film still kept a good resolubity.
