Top 100 Key Players companies in Polypropylene glycol
by Most Patent Citation in the Japan in 2019

The Polypropylene glycol top 100 is Discovery PatSnap’ annual ranking of the top 100 Most Patent Citation Polypropylene glycol Key Players in the Japan. Discovery has identified the top key players, startups & unicorns, fast-growings, news entrants in 2019, ranking from differnt perspectives, including patent filing intensity, academic research capability, news media heat. The company list is generated from various data types.
Polypropylene glycol or polypropylene oxide is the polymer of propylene glycol. Chemically it is a polyether, and, more generally speaking, it's a polyalkylene glycol (PAG). The term polypropylene glycol or PPG is reserved for low to medium range molar mass polymer when the nature of the end-group, which is usually a hydroxyl group, still matters. The term "oxide" is used for high molar mass polymer when end-groups no longer affect polymer properties. In 2003, 60% of the annual production of propylene oxide of 6.6×10⁶ tonnes was converted into the polymer.
