ABSTRACT

 

Plasticizers are used in paints and plastics to impart and promote plasticity in them. Plasticizers or dispersant are additives that increases the plasticity and fluidity of a material. They often based on esters of polycarboxylic acids with linear or branched aliphatic alcohol of moderate chain length. Technology involved in the working of plasticizers shows that they embedded them self between the chain of polymers , spacing them apart i.e. increasing the free volume and thus significantly lowering the glass transition temperature for plastics and paints and making them softer by lowering their cold flex temperature and increasing flexibility. The paper reports the technological modifications in the manufacture of plasticizers for paints and plastics. Plasticizer manufactured from value added products from vegetable oils gives remarkable products.
