Synthesis and Physicochemical Properties of Polyalkyds

Tir-tex是一家在加拿大设有研发部门的公司，生产聚合物、树脂、颜料、建筑产品和表面活性剂。公司需要生产高质量的聚醇酸树脂。在这种情况下，需要在这些聚合物的合成和分析其物理化学性质的坚实的知识。因此，本Engage项目的目的是研究从大豆油合成聚醇酸树脂的不同反应条件，并确定其物理化学性质。事实上，聚醇酸的分子量和链长分散性对于目标应用是非常重要的。因此，通过微调它们的合成条件，我们将首先合成具有良好定义的分子量和链长分散度的聚合物。接下来，将使用诸如差示扫描量热法（DSC）和傅里叶变换红外光谱（FTIR）的技术，以分别确定聚醇酸树脂的玻璃化转变温度和化学组成。这些性质对于评估其应用范围很重要。我们相信，拟议项目的结果将有助于扩大生产线，增加加拿大Tri-tex的员工，并将有助于将这些聚合物提供给加拿大其他工业部门，并增加其在涂料领域的生产和商业利益。

Tir-tex, a company with R&D department in Canada, produces polymers, resins, pigments, construction products and surfactants. The company needs to manufacture polyalkyds with high quality. In this context, a solid knowledge in the synthesis of these polymers and the analysis of their physicochemical properties is required. Therefore, the objective of this Engage project is to investigate different reaction conditions to synthesize polyalkyds from soya bean oil and determine their physicochemical properties. In fact, the molecular weights and chain length dispersities of polyalkyds are of substantial importance for the targeted applications. Thus, by fine tuning their synthesis conditions, we will first synthesize polymers with well defined molecular weights and chain length dispersities. Next, using techniques such as differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR) will be used in order to determine the glass transition temperature and chemical composition of polyalkyds, respectively. Such properties are important to evaluate their scope of applications. We believe that the outcome of the proposed project will help expand the manufacture lines and increase the staff of Tri-tex in Canada as well as will help to deliver these polymers to other Canadian industrial sectors and increase their production and commercial benefits for Canadians in the field of coating materials.
