The research on bound rubber and reinforcing effect of mineral filler showed that there are four kind of interactions between filler and rubber matrix in uncured mix The unbounded rubber on the surface of filler will solve in organic solvent The rubber bounded by stronger physical or chemical interaction with filler will dissolve in organic solvent The bound rubber on the surface of filler by different extent acid-base interactions will solve in basic organic solvent The bound rubber on the surface of filler by chemical action (no acid-base type) will dissolve in basic organic solvent

结合橡胶和增强作用的研究表明，在混炼胶中，硅橡胶与矿物填料的作用形式有四种。没有联结在矿物表面的非结合橡胶和仅靠物理吸附联结在填料表面的硅橡胶将溶解于有机溶剂；与填料有较强相互作用的硅橡胶不溶于有机溶剂；通过不同层次的酸碱作用联接在矿物表面的硅橡胶将溶解于碱性有机溶剂；与填料有牢固化学结合的硅橡胶不溶于碱性有机溶剂。

Chitosan had been modified by polyacrylate sodium, glularaldehyde, and NaBH4, respectively, which afforded three kinds modified chitosan: polyacrylate sodium modified chitosan (CIS- PA4) chitosan bead and pentamethylene diamido crosslinked chitosan bead (CTSB- G- Hy). The adsorption properties of CTS-CTSB and CTSB-G-Hy were studied by L25(56) orthogonal experimental design. They show high adsorption activities for Pb2+ in solution. The highest removal efficiency of Pb2+ for CTS-PA4, CTSB and CTSB-G-Hy is 94%, 96% and 93%, respectively. The results showed the adsorption property of CTSB is the highest. The CTSB- G- Hy has good mechanical property, acid-resistance and alkali-resistance.

第二部分壳聚糖的改性及其对水溶液中铅离子的吸附性能研究以壳聚糖为原料制备了三种改性吸附剂——聚丙烯酸钠改性壳聚糖(CTS——PA_4)、珠状壳聚糖凝胶树脂和戊二氨交联珠状壳聚糖凝胶树脂，着重考察了CTSB—G—Hy的制备条件，并考察了三种吸附剂吸附6.3mg/L铅离子水溶液中铅的最佳使用条件，结果表明对CTS—PA_4而言当pb~(2+)溶液的pH在4～6.5之间，吸附剂用量为5g/L，吸附时间为1h时pb~(2+)去除率高于94％，CTS—PA_4可在酸性条件下使用，在碱性条件下依然有效但处理效果较差；CTSB对pb~(2+)具有很好的吸附能力吸附剂用量为5g/L，吸附时间为1h时处理效果极佳，pb~(2+)去除率高于96％；CTSB—G—Hy对pb~(2+)具有一定的吸附能力，吸附剂用量为3g/L，吸附时间为1.5h时处理效果最佳，Pb~(2+)去除率高于93％，而且CTSB—G—Hy的机械强度高，耐酸碱性强，可在较宽的pH范围内使用。

结果表明：在中性水环境中，贝体能积极地从外界水环境中吸收钙，并能旺盛地合成和分泌贝壳珍珠层及珍珠有机基质前体物质；持续的酸性水环境导致贝体的钙严重丢失，并引起珍珠质分泌细胞对有机基质前体物质的合成和分泌能力减弱；持续的碱性水环境虽能导致贝体对钙的积累，但珍珠质分泌细胞合成和分泌珍珠质有机基质前体物质的能力减弱；水环境的酸性或碱性程度越高，对珍珠质分泌细胞的合成和分泌活动的影响越大。

The analysis of polymer structure indicates that the non-crystalline phase is the majority of the agglomerate structure and the crystalline phase is the minority, the highest crystal value only reaches the level of 0.1646;There is a definite interactionadditives and PVA, which not only reduces the crystal value of ASPE to make amorphous areas enlarge but also improve the ability of segmental motion by destroying the well-regulated and orderly character of polymer chain, meanwhile restricts the mobility of potassium cation and enhances the anionic transference number of hydroxide ions, all these improve the ionic conductivity;The ionic conductivity occurs essentially within the amorphous phase of the ASPE;The structure of ASPE doesnt change in the range of our test temperature, this means, the temperature only takes effect on degradation of complex in certain compositions, ionic mobility and segmental motions of the polymer chain.

聚合物结构分析表明：碱性固体聚合物电解质中凝聚态结构以非晶态为主，仅有少量的晶态，结晶度最大为0.1646；添加的各组分与PVA之间都有一定的相互作用，这种作用不仅破坏了聚合物链段的规整性，能够降低聚合物的结晶度，增大无定形区域，提高链段运动的能力，同时这种作用限制K~+离子的运动，提高OH~-的迁移率，从而提高离子电导率；碱性聚合物电解质的离子传导主要发生在无定形区；在本实验测试离子电导率温度范围内，聚合物内部的结构不会发生变化，即温度只会影响电解质内部络合物解离程度和载流子迁移以及聚合物链段运动的情况。
