PTT工程塑料的开发和应用

介绍聚对苯二甲酸丙二酯(PTT)基础树脂的合成工艺路线及其主要原料1，3-丙二醇(PDO)的生产工艺路线。阐述了PTT树脂的发展概况和现状，国际主要生产商的发展动向，国内PTT树脂和原料PDO的开发状况及建设规划。比较了PTT、PET、PBT、PA66和PC的纯树脂品级和玻璃纤维增强品级的性能，概述了PTT的开发和应用状况，介绍了商业化系列PTT产品的牌号和性能，并展望了PTT的市场前景。

DEVELOPMENT AND APPLICATION OF PTT ENGINEERING PLASTICS

The synthetic routes for the base resins of polytrimethylene terephthalate(PTT) and the process of 1,3-propanediol (PDO) which is the primary monomer of PTT were introduced. The development and present situation for PIT resin, the developing trend of PTT resin's producers in the world, the development and building plan for PTT resins and PDO in China were also introduced. The performances for PTT, PET, PBT, PA66 and PC were compared in both pure resin grade and glass fibre reinforced grade. The development and application for PTT were summarized. The trademarks of the property of the commercial series PTT products were detailed. The prospect for the PTT market was forecast.
