WebThe glass transition temperature of these polymers typically ranges from -80°C to +100°C. The Tg can be manipulated by varying the polymer composition. For example, in a styrene … WebApr 12, 2024 · The polymer nanocomposites showed improved crystallinity and glass transition temperature values compared with the PPS resin. The appearance of a rubbery trend in the glass transition peak, with a decline in value of up to 6% of the filler mixing, is indicative of easy molding due to the introduction of the amorphous character.
