Scope

Scope: This document specifies the overall design, process technology, evaluation indicators, and pollution control of in situ chain extension-modified recycled plastic particles. This document is applicable to waste plastics that can generate hydroxyl, carboxyl, and other groups after aging, such as waste polystyrene plastics containing unsaturated double bonds. These groups can undergo an in situ chain extension chemical reaction with chain extenders through chemical reactions.
