        摘要：In this paper,the advantage and disadvantage of MC nylon as one type of engineering plastics were briefly introduced and the aim of modification of which in practical applications was discussed. Based on modified mechanism of rigid inorganic particles on polymer,with the special structure characteristics of zeolites and its now applications in polymer,a series of model and mechanism of MC nylon reinforced and toughened by zeolites were firstly proposed. In addition,the prospect of polymers modified by zeolites were outlined.

        摘要：Polymer particles containing bithiazole group were synthesized with2,2-diamino-4,4-bithiazole and benzidine. The particles were characterized with FT-IR spectroscopy,thermogravi metric analysis and scanning electron microscopy. Electrorheological (ER) fluids were prepared by disperse the polymer into two different media of bromodiphenylmethane and silicone oil respecti vely. Rheological properties of the ER fluids were measured with a rotational rheometer. Effects of electric field strength,disperse phase concentration and different disperse medium on the ER fluids were measured and discussed. The results showed that ER behaviour was enhanced with an increase in the disperse phase concentration and in the electric field strength. ER behaviour with density match is better than that with density mismatch between disperse phase and disperse medium.

        摘要：Tetraethoxysilane ( TEOS) , methyl methacrylate ( MMA) and 2-hydroxy propyl methacrylate ( HPMA) were used to prepare SiO2/PMMA hybrid quasi-gels by sol-gel method .The hybrid quasi-gels were used to modify PP as filler .FT-IR 、XRD 、SEM and PLM were employed to study the structure of PP/SiO2 hybrid nanocomposites and the relationships among property , structure and composition of these composites were studied at the same time .The results show that PMMA/SiO2 hybrid quasi-gel can induce PP to form β crystal and minimize the spherulite size in PP .When the content of SiO2 in PP/SiO2 hybrid nanocomposite ( PSH) is 2 %( wt) , the toughness strength is increased by 81 % than pure PP .
