Crystallization of polymers - Wikipedia

Crystallization of polymers is a process associated with partial alignment of their molecular chains. These chains fold together and form ordered regions called lamellae, which compose larger spheroidal structures named spherulites. Polymers can crystallize upon cooling from melting, mechanical stretching or solvent evaporation. Crystallization affects optical, mechanical, thermal and chemical properties of the polymer. The degree of crystallinity is estimated by differe… WebDec 22, 2024 · The effect of polymer architecture, i.e. the position of the TMSPMA groups on the polymers, on bonding between networks, mech. properties, biodegrdn. rate and 3D … WebThe polymer aggregation of the solution decreases with increasing Te from room temperature to 50 °C, but the maximum aggregate growth rate is obtained at T e = 40 °C.
