Oil and polyol firstly hydrolyze, and then react with maleic anhydride to give semi ester, the residual maleic anhydride hydrolyzing to give maleic acid, finally are adducted with DCPD. The result of experiment shows that the synthesized resin is of perfect air drying performance and improved flexibility and anti-greening because of the use of oil, meetin...

试验结果表明，油与多元醇在210～220℃下先醇解，然后与顺酐反应形成半酯，剩余顺酐水解成顺丁烯二酸，然后与DCPD加成，合成的树脂具有优良的空干性；同时油的使用极大地提高了涂膜的柔韧性和抗绿化性，得到的树脂性能上可满足涂料用不饱和聚酯树脂的要求。

Cellulose acetate butyrate,which is widely applied as coatings additive, is synthesized in the heterogeneous system. The activation is required because of the strong hydrogen intramolecular and intermolecular bondings and the regulation of the crystalline region in cellulose microfibrils.

中文摘要纤维素醋酸丁酸酯（Cellulose acetate butyrate是一种广泛应用于涂料工业的添加剂，由于纤维素具有分子内与分子间强氢键作用以及纤维素纤维的局部规整的结晶序列等特征，一般纤维素在酯化反应前都需要进行预活化处理，工业上纤维素醋酸丁酸酯的合成方法一般都在非均相体系中进行的。

Phthalic acid esters are widely used in the many fields of industry. So many countries including China have come to pay attention to them and make up the codes for limiting the content in some products such as textile. By combining international codes, the thesis selects coating and textile that have close relative with people as objections. The research results are as follows:1. The thesis has established the textiles preparation method by a series of experimentations such as extraction solvent, extraction time, solid-phase extraction. The average recoveries of eleven phthalates are from 80.30% to 98.00%, and the relative standard deviations from 0.59% to 2.56%, the results show that this method is accurate and credible.2. The thesis set up the simultaneous determination of benzene, toluene, xylenes and phthalates in coatings.

邻苯二甲酸酯类化合物被广泛地应用在工业领域的各个方面，国际上已经开始重视邻苯二甲酸酯作为一种内分泌干扰素的危害性，对在一些产品中的用量作出了限制，但没有具体的分析测定方法，本论文结合国际法规选择了与人们生活密切相关的涂料和纺织品来研究其中邻苯二甲酸酯类环境激素的测定方法，研究内容如下：(1)通过对提取溶剂、提取方式、提取时间的选择实验以及固相萃取的一系列条件实验，首次建立了纺织品中测定邻苯二甲酸酯类环境激素的前处理方法，并对分析方法作了准确度、精密度验证。
