Stabilisers for polymers derived at least in part from phenolic monomers are made by polymerisation of: EITHER LACTONES, LACTAMS, OR REACTIVE AMINE COMPOUNDS, AND OPTIONALLY DIBASIC ACIDS ALSO, OR THEIR PRE-POLYMERISATES, WITH PHENOL ACIDS OR ESTERS OR HALIDES THEREOF OR ALTERNATIVELY LACTONES, LACTAMS, OR ACIDS OR ACID HALIDES, AND OPTIONALLY DIAMINES ALSO, OR THEIR PRE-POLYMERISATES, WITH PHENOLIC AMINES. |
