聚合物共混物的性能在很大程度上取决于组分的类型，也取决于混合方法，包括组分的添加顺序。这种影响主要表现在力学性能、热性能和加工性能的变化上。聚合物材料达到均一性、特定结构和性能的基本条件是聚合物的相互混溶。通常使用使混合更容易的附加剂；它们具有反应效应，导致输出聚合物的化学修饰以及其化学结构和大分子链结构的变化。为了达到这一目的，人们使用了低分子质量(12+/-2K)的聚乙烯吡咯烷酮(PVP)。PVP具有生成络合物的能力强的特点，这是PVP作为一种高吸附能力的试剂被应用于医药和纺织工业中用于稳定着色剂的原因。Polyond 3150-热塑性马来酸酐也被用作相容剂，用作偶联聚丙烯(PP)均聚物改性的化学试剂。它既是制造工艺的稳定剂，也是提高耐老化和耐高温性能的稳定剂。在本工作中，给出了添加聚乙烯吡咯烷酮和聚键的PP与聚酰胺(PA)以及不同比例组成的PP/PA共混物的一些性能选择结果。研究了不同类型的填料对所制备的共混物性能的影响。采用碱性氧化物含量小于1%的硼铝硅E玻璃和钛白粉(TiO2O4)制成的代号为E的玻璃纤维作为填料。(C)2005 Elsevier B.V.保留所有权利。
The properties of the polymer blends depend significantly on the type of the components and also on the mixing method including the order of the components adding. That kind of influence manifests especially in the change of the mechanical, thermal and processing properties. The basis condition for reaching the homogeneity, specific structure and the properties of a polymer material is its mutual miscibility of the polymers. Additional agents that make mixing easier are usually applied; they have reactive effect which results in a chemical modification of output polymer along with the change in its chemical structure and the structure of macrochains. In order to achieve this, the polyvinylpyrrolidone (PVP) with low molecular mass (12 +/- 2 k) has been used. PVP is characterized by high ability to create complexes which is the reason that it has been applied for the medicine as an agent with high sorption ability and in the textile industry for stabilizing of colouring agents. Polybond 3150-thermoplastic maleic anhydride has also been used as a compatibilizer used as a chemical agent coupling the modification of the polypropylene (PP) homopolymer. It is a stabilizer both for the manufacturing processes and the one that improves the resistance to ageing and to high temperature. Within the work some results of chosen properties of PP and polyamide (PA) and PP/PA blends with different percentage composition with the addition of polyvinylpyrrolidone as well as polybond have been presented. The investigations for the influence of the fillers of different types on the properties of prepared blends have also been conducted. As a filler a glass fibre with its symbol E made of the boron-aluminium-silicon E-glass with the alkaline oxides content of less than 1% and titanium white (TiO2) have been used.
