Polymerisation Recycling techniques

As the reader has observed in this review, the innovation process is thriving within this new environment. The focus has been on more cost effective polymerisation plants with an improved environmental profile, the replacement of lead stabilisers, scientific studies and support for phthalates, a greater understanding of and an increasing role for impact modifiers, recycling techniques and waste management possibilities. 

Bulk polymerisation techniques are usually carried out as continuous or semi-continuous processes. Polymerisation is restricted to a low degree of conversion and is stopped while the viscosity of the reaction mass is still low enough to allow effective agitation. Ibe urueacted monomer is removed and recycled.
