Abstract Fine and ultrafine denier polypropylene fibers are high-tech achievements developed independently by China in the 1980s and 1990s,reaching an internationally leading level.From 1987 to 1997,China successfully achieved industrial production of fine and ultrafine denier polypropylene filaments and completed the transformation of scientific and technological achievements through three stages:advanced research,technological development and industrial trials,and industrialization.This process not only served as a model for China’s industry-university-research cooperative development projects but also reflected the transformation of China’s scientific and technological activities and operational mechanisms against the backdrop of scientific and technological transformation.During this period,the Institute of Chemistry,Chinese Academy of Sciences provided solid support for the research and development,industrial production,and commercialization of fine and ultrafine denier polypropylene fibers through research on the spinning process,development of specialized materials,spinning technology development,and the establishment of technology companies.This paper focuses on the work of the Institute of Chemistry,systematically examines its participation in the entire process of research and development and industrialization of fine and ultrafine denier polypropylene fibers,analyzes the organizational models and characteristics of China’s high-tech industry-university-research cooperative innovation against the backdrop of scientific and technological transformation in the 1980s and 1990s,discusses the role and key functions of the Chinese Academy of Sciences in this process,and extracts lessons learned from the operational experience in science and technology to provide a historical reference for scientific and technological development in the new era.
