Residual styrene in CIPP – Material and environmental impacts

Styrene serves as a reactive thinner in UP and VE resins. During heat- or light-induced curing of CIPP, styrene leads to three-dimensional crosslinking of the resins. If this polymerization proceeds incompletely, this results in unfavorable residual styrene. The lecture gives an explanation to the background and effects of residual styrene on materials properties and the environment.
