Polyethylene Glycol (PEG) is a versatile polymeric compound that can be used in several industries including automotive, chemical, pharmaceutical, personal care, and plastics. Personal care industry was the one of the major application segments for polyethylene glycol in 2019 and projected to experience healthy demand growth over the forecast timespan. The gercatalyst in the reaction mixture. This is followed by a reduction as shown. This invention relates to an improved method for the manufacture of polymeric glycol ter-' ephthalates and more particularly to such a method which employs a novel and effective by the aid of catalysts known to the art is polymerized by means of heat, the heating being carried out in the presence of a germaniumcontaining material as catalyst. Where the term lower alkyl esters is used, moreover, we intend this to include only esters of alcohols containing not more than four carbon atoms. Medical & pharmaceutical was the major application segment and accounted nearly 40% share in 2019. stream The medical & pharmaceutical application segment registered a major share in 2019 and is anticipated to record a remarkable growth rate throughout the forecast period.
