Polyester is primarily considered a copolymer, particularly because it is made through a polymerization process that involves condensation of a diol (ethylene glycol) and a dicarboxylic acid (terephthalic acid). In this context, the resulting polyester, often referred to as polyethylene terephthalate (PET), includes repeating units derived from both components, categorizing it clearly as a copolymer. Homopolymers, in contrast, are polymers derived from a single monomer type, which is not the case for polyester. However, various forms of polyester can exist, and the term can broadly refer to a group of polymers that contain the ester functional group in their main chain. While PET is the most widely recognized and used polyester, there are also homopolyesters, which are not as common in everyday applications as PET. This distinction is crucial in understanding polyester’s versatility and wide range of applications, from textiles to packaging materials.

Tianjin Bohai, a prominent player in China’s petrochemical landscape, has successfully resumed the production of propylene oxide at its facility located in Tianjin, China. The restart operation, which took place on October 25, marks a significant milestone, as it follows a temporary shutdown necessitated by a technical breakdown. Repair activities at the facility, which possesses an impressive production capacity of 200,000 metric tons of propylene oxide per year, were initiated on October 21 to address the technical issues.Prior to this development, Tianjin Bohai had made headlines for the resumption of ethylene and propylene production at a methanol-to-olefins (MTO) plant in Tianjin, China. This particular facility, boasting a substantial capacity of 1.8 million metric tons per year, plays a pivotal role in the production of ethylene and propylene, with production capabilities amounting to 328,000 metric tons of ethylene and 349,000 metric tons of propylene per year. The tempor...
