25891.不饱和聚酯酰胺树脂/纳米羟基磷灰石复合材料的制备及其性能研究
[橡胶和塑料制品业,化学原料和化学制品制造业] [2014-09-17]
本文以顺酐、苯酐、乙二醇(MEG)、新戊二醇(MNG)、甘氨酸等为原材料,通过熔融缩聚法,合成了一种新型的不饱和聚酯酰胺树脂并用苯甲醇进行了割端以在降解过程中提高交联后的树脂的耐水胜能。列不饱和聚酯酰胺树脂进行了表征。以乙酸乙烯酯为交联剂,过氧化苯甲酰(BPO)为引发剂,N,N-二甲基苯胺为促进剂,把n-HA引入基体,通过原位聚合法制备出不饱和聚酯酰胺树脂/n-HA生物医用复合材料。并对复合材料的弯曲性能和降解性能进行了研究.

25892.行业月度报告-化工201407
[橡胶和塑料制品业,化学原料和化学制品制造业] [2014-09-15]
7月,在微刺激政策下,宏观经济出现回升迹象,化工行业工业增加值增速改善。 1~7月,化工行业增加值同比增长11.0%,增速同比提高0.1个百分点。从主要产品产量看,化肥、合成树脂、化纤产量增速有所回落,橡胶产量增速出现反弹。化工各子行业出厂价格指数继续以升为主,但仍低于100点,化工产品价格继续低于上年同期水平。7月份,随着工业需求回暖,国内化工市场逐步上行,相比去年同期市场活跃性及产品成交价格均大有起色。但是同时,多数化工产品仍面临产能过剩、库存高企等问题,化工产品价格依然处于历史低位。
