421.聚乙烯醇/羧甲基纤维素钠交联微球的制备及性能研究
[橡胶和塑料制品业] [2015-05-31]
采用反相悬浮法制备聚乙烯醇(PVA)/羧甲基纤维素钠 (CMC-Na)交联微球。通过正交法探讨了戊二醛用量、原料配比、催化剂用量以及反应温度对产率和平衡溶胀率的影响;采用红外光谱、扫描电镜对微球的化学组成和表面形貌进行分析,并研究了微球在不同pH条件下的溶胀行为。正交试验结果表明,最优实验方案下微球产率达到88.89%。红外光谱和扫描电镜测试结果表明,反应生成了PVA/CMC微球,微球球形度和分散性优良,粒径分布均匀,微球平均粒径为195μm。溶胀性能研究表明,在酸性环境中微球先溶胀后退溶胀;在碱性环境中微球不断溶胀直到溶胀平衡,且在碱性环境中微球的平衡溶胀率1.75远大于在酸性环境中的平衡溶胀率0.89,微球表现出pH敏感性。根据微球的pH敏感性,有望作为结肠靶向药物载体材料。

422.含POSS的纳米杂化物对环氧树脂改性研究
[橡胶和塑料制品业] [2015-05-31]
将笼型八聚倍半硅氧烷(POSS)与对-甲苯基缩水甘油醚 (TGE)反应,合成了顶角含有苯环的笼形八聚倍半硅氧烷无机/有机纳米杂化物(PTGE),将该杂化物添加到双酚A型环氧树脂(E44)中对其改性,测定固化后改性环氧树脂复合材料的力学性能和热稳定性能。结果表明,改性后环氧树脂的冲击强度、拉伸强度和断裂伸长率较改性前有了明显的提高,热稳定性大大增强。

423.ADR扩链对PLA/PC共混物结构与性能的影响
[橡胶和塑料制品业] [2015-05-31]
以环氧扩链剂ADR-4368CS为增容剂,采用熔融共混制备了不同质量配比的聚乳酸/聚碳酸酯(PLA/PC)共混物,通过扫描电镜(SEM)、核磁共振仪(NMR)、差示扫描量热仪(DSC)以及拉伸和冲击测试等,分析了ADR对PLA/PC共混物的流变性能、相形态、热性能及力学性能的影响。结果表明,PLA/PC中加入ADR能有效提高共混物界面黏结力,促进了共聚物的生成,相容性得到改善,且共混物黏度提高;SEM显示,ADR的加入使PC分散相尺寸减小,PC分布均匀;DSC测得加入ADR后,体系中PLA分子链运动更加困难,结晶能力降低。材料韧性明显改善,尤其对于B50,断裂伸长率与冲击强度分别为163.9%和72.9 J/m。

425.北美医药包装市场报告（2015-2019年）
[医药制造业,造纸和纸制品业,橡胶和塑料制品业] [2015-05-13]
The purpose of packaging products is to protect perishable goods from external damage and contamination. Pharmaceutical packaging products have high-barrier properties, are portable, and available in both unit dosage and multi-dose formats, thereby ensuring the extension of their shelf life. Regulatory bodies for drug manufacturers strictly enforce international jurisdictions on safe drug delivery. This has fueled the adoption of sustainable packaging. Plastic resins, glass, paper and paperboard, aluminum, and other metals are used in the manufacture of pharmaceutical packaging products. These products are available in a variety of dimensions and forms.

428.全球农业用薄膜市场报告（2015-2019年）
[橡胶和塑料制品业,农、林、牧、渔业] [2015-05-11]
Agricultural films are new-age films that are a component of modern farming technologies used to increase farm productivity. They are generally made from a variety of plastic resins such as different grades of PE, EVA, PVC, and PVOH. They offer a wide range of benefits in mulching, silage, and greenhouse applications such as soil temperature and moisture control, elimination of weeds, enabling lesser use of herbicides, storage and growth of crops in greenhouses, and prevention of soil erosion, in addition to protecting cattle fodder in silage bales. But, owing to disposal and pollution hazards, they are facing competition from non-biodegradable alternatives. The key customers of agricultural films are crop growers, processors, and retail packagers, who are the major stakeholders across the agricultural and horticultural sectors.
