摘要: Abstract Structure of polycaprolactone (PCL) crystallized in a wide concentration range was investigated to correlate entanglement content with the formed structure. Mixed solvent constituted by good solvent chloroform and nonslovent ethanol was used to control the concentration crystallization started (c onset, weight fraction), which varied from 0.13 to 0.53. Crystallization at higher c onset was achieved by electrospinning and melt crystallization. The concentration correlates with entanglement number (N) by the scaling law N/N 0= ϕ 1.3 …
