Why pvc has low glass transition temp than polyvinyl alcohol? |
|
Answer» g, thermoplastics become increasingly viscous and eventually MELT. Decomposition OCCURS at SUFFICIENTLY high temperatures. We can see that polyisoprene with a Tg of -75°C is SOFT or rubbery at roomtemperature, polyvinyl chloride or PVC has a Tg of 82°C and is rigid at roomtemperature. |
