Sulphur polymers for eco-friendly plastics
from Lab News
Currently, the process of reacting sulphur with organic crosslinker molecules to make it stable – known as inverse vulcanisation – involves long reaction times and high temperatures and results in harmful by-products. Researchers at the University of Liverpool found that the addition of a small amount of zinc diethyldithiocarbamate to the process reduces temperatures and reaction times. It also increases reaction yields, improves physical properties of the polymers and prevents production of harmful by-products.
