Abstract
Thegeneralized utilization of polymeric materials in
every dayhuman life sets a crucial problem as far as fire-
retardant is concerned.
Polypropylene (PP) is the fourth main bulk plastic produced in the world after polyethylene, poly(viny) chloride) and polystyrene.
The purpose of the present worK is not only to increase the flame retardance of polypropylene by means of the incorporation of zinc chelates, but also to investigate the mode of actions of such additives.
It was meant to introduce the subject by giving a Idetailed accounts on the combustion of organic polymers and |the associated thermal decomposition mechanisms. Previous irKers have dealt with this subject in various ways such as the use of metal oxides, halogen compounds and metal complexes to inhibit the thermal oxidation of polypropylene.
