1,2-Benzenedicarboxylic acid, polymer with (2Z)-2-butenedioic acid and ethenylbenzene - Introduction
The polymer of 1,2-benzenedicarboxylic acid with (2Z)-2-butenedioic acid and vinylbenzene is a polyester-type high molecular compound and is commonly referred to as polyethylene terephthalate (PET). It has the following properties:
1. Physical properties: Polyethylene terephthalate is transparent, has good physical strength and durability, and also has good heat resistance and chemical resistance.
2. Thermal properties: The melting point of PET is higher, generally about 240-260 degrees Celsius. It has good thermal stability and can withstand high temperature processing.
3. Mechanical properties: PET has excellent mechanical properties, including high tensile strength, impact resistance and stiffness.
4. Transparency: PET has good transparency, even comparable to glass, so it is widely used in the manufacture of transparent plastic containers and packaging materials.
The main uses of polyethylene terephthalate include:
1. Food and beverage containers: Because PET has good chemical resistance and transparency to food and beverages, it is usually used to make bottled beverages, food boxes, juice bottles, etc.
2. Fibers and textiles: PET fibers are used to manufacture various textiles, such as clothes, bed sheets, carpets, etc. It has good abrasion resistance and anti-fading properties.
3. Medical applications: Because PET has good biocompatibility, it can be used in the manufacture of medical equipment, surgical instruments and packaging materials for medical purposes.
The method for preparing polyethylene terephthalate is to esterify 1,2-benzenedicarboxylic acid with (2Z)-2-butenedioic acid and vinylbenzene to obtain a polymer.
Regarding safety information, PET is considered to be a relatively safe plastic material suitable for food contact and medical applications. However, harmful substances may be released when PET is processed in a hot state, so ventilation and protective measures need to be paid attention to during processing. At the same time, PET has a certain degree of flammability, and it is necessary to avoid contact with high temperature and open flame during handling and storage. The correct use and handling of PET materials is very important to ensure safety.
