Abstract

Carbon black Hydrolysis Polyethylene Polyethylene terephthalate Polymerization Polypropylene
Geotextiles are commonly made from polypropylene, polyethylene, or polyethylene terephthalate. The polymerization processes of these three types of polymers are described in this chapter. For polypropylene and polyethylene, there has been a significant advancement in polymerization processes, particularly in the innovative development of new catalysts and modern design of the reactors. For polyethylene terephthalate, the batch process and continuous process are summarized. Furthermore, the sensitivity of the polymerization temperature to the hydrolytic property of the polymer is described. The function of processing stabilizers and carbon black that are incorporated into polypropylene and polyethylene before the manufacture of geotextiles is also explained.
