MMA-天然橡胶接枝聚合物表面的酸碱作用
ACID-BASE INTERATION OF THE SURFACE OF MMA-NATUAL RUBBER GRAFT POLYMERS
【摘要】 <正> 聚合物-基体界面的酸碱配位作用是界面粘合力形成的重要因素之一,Fowkes,Drago,Matsunaga等曾对参照液体-聚合物体系粘附功的酸碱作用成份的测算方法进行了研究,并测定了乙烯、丙烯酸、纤维素等聚合物表面的酸碱属性。本文应用Fowkes的基本方法,对MMA(甲基丙烯酸甲酯)-天然橡胶接枝聚合物表面的酸碱属性及其对基体的粘合力的影响进行了研究。
【Abstract】 Acid-base interactions of the surface of MMA-natual rubber graft polymers in some liquids were studied by detecting the adhesion work and it’s dispersion components. To the systems of the acidic liquid (phenol/tricresyl phosphate solution)-basic surface of graft polymers, acid-base interaction is present in interface. The contribution of adhesion work of this interaction, which did not take place in basic liquid (formamide)/graft polymer’s systems, is increased with the increasing of the MMA content in this polymer. In addition, the adhesive strength of the joints of the graft polymer-glass substrate is also changed apparantly resulting from the difference of the acidic/basic property of the substrate obtained through surface treatment.
