摘要
In granulation of stabilisers for vinyl polymers contg. halogen by dispersing waxy, low-melting components in aqs. dispersion of stabiliser, removing dispersion medium and drying, molten waxy component is injected under pressure into aqs. dispersion. Process is technically simple and gives free running, non-dusting granulate, which can be stored without unmixing.
