Polyvinyl chloride glass transition temp
http://www.plastemart.com/plastic-technical-articles/polyvinyl-chloride-pipes-in-rainwater-harvesting/1152 WebThe temperature below which the polymer becomes hard, brittle and glassy and above which it is softener and flexible, is known as glass transition temperature (TG). The glass transition is a property of only amorphous portion of a semi-crystalline solid. The crystalline portion remains crystalline during the glass transition.
