Base on the production of SG-7 resin, not only the commercial formulation and process parameters of 30 m3 polymerizer were adjusted for special resin of injection pipe, but also the formula weight control, ?°fish eyes?± reduction, particle shape optimization, and heating ageing were improved. The resin has better properties, including plasticization, rheological property and heat resistance.
