About Us

Precision Polymer Technologies Co., Ltd. is a technology company founded to commercialize research from the University of Science and Technology of China (USTC) through a program that grants rights to research outcomes. The company develops precision polymers for biomedicine and key functional materials. It aims to move beyond conventional polymers characterized by average molecular weight, dispersity, and average composition by defining molecular composition, chain length, sequence, and structure, making material performance easier to control and predict. Its focus areas include single-molecular-weight precision polyethylene glycol (PEG) and its derivatives, precision PEG lipids, polyether and polyester pharmaceutical excipients, and biomedical polymers. Its capabilities span molecular design, precision synthesis, structural characterization, functional evaluation, and scale-up manufacturing, with applications in pharmaceutical excipients, nanomedicine, nucleic acid delivery, high-performance resins, and advanced electronic chemicals.

Building on this foundation, the company is developing methods to control copolymer composition, sequence, and microstructure. Precise measurements of monomer reactivity ratios, polymerization kinetics, and composition drift help establish quantitative links among monomer structure, reactivity, sequence distribution, and material performance. The company is expanding into biodegradable polyesters such as poly(lactic-co-glycolic acid) (PLGA), as well as polypeptides, DUV and EUV photoresist resins, carbon fiber precursors, self-healing coatings, and other key functional polymers. It is also developing an AI and automation platform for polymer R&D that combines automated synthesis, online spectroscopic and chromatographic analysis, high-throughput experimentation, reaction kinetics modeling, and machine learning to build and continually update a high-quality polymerization database. Its closed-loop workflow cycles through automated experiments, real-time analysis, model training, formulation and process optimization, and experimental validation. The platform supports polymerization parameter prediction, copolymer sequence design, and the inverse design of materials for target properties, moving polymer R&D from empirical trial and error toward data- and AI-driven development.

The company’s guiding principle is "Molecular precision defines materials. Precision materials shape the future." For the life sciences and healthcare, it also uses "Molecular precision defines materials. Precision materials advance health." The company aims to build an internationally competitive platform for precision polymers and AI in chemistry. Its capabilities span precision molecular design and synthesis, automated experimentation, data modeling, scale-up manufacturing, and validation in end-use applications. Serving the life sciences and healthcare, advanced manufacturing, and key functional materials, the platform helps move polymer R&D and manufacturing beyond controlling average properties toward well-defined materials, predictable processes, and performance that can be designed for specific applications.
