Polymer chemistry is an integral part of art conservation graduate training programs. The list of materials used by artists and artisans and by conservators is vast, with the majority being polymeric in nature. Conservators use an array of polymers as coatings, adhesives, fills, supports, and structures. Aside from the chemistry of these materials, all students need to have a good understanding of their thermal behaviors. This includes mechanical and physical changes due to thermal transitions, such as glass transition and melting. Additionally, students need to have some understanding of blending polymeric materials and miscibility, especially if they are tailoring a material to behave in a particular way. Differential Scanning Calorimetry (DSC) lends itself well to investigating the thermal transitions of polymer blends and their compatibility. This paper will present a practical laboratory exercise that explores both polymer miscibility and thermal transitions in the context of art conservation materials.

艺术保护研究生的差示扫描量热法：使用聚合物共混物的实用实验室练习

高分子化学是艺术保护研究生培训计划不可或缺的一部分。艺术家和工匠以及保管人使用的材料种类繁多，自然界中大多数是聚合材料。储油柜使用一系列聚合物作为涂料，粘合剂，填充物，支撑物和结构。除了这些材料的化学性质以外，所有学生都需要对他们的热行为有很好的了解。这包括由于热转变（例如玻璃转变和熔化）而引起的机械和物理变化。此外，学生需要对混合聚合物材料和混溶性有一些了解，特别是如果他们正在对材料进行定制以使其具有特定的性能。差示扫描量热法（DSC）非常适合研究聚合物共混物的热转变及其相容性。
