POLYMER CRYSTALLITES WITH FEW TIE MOLECULES FROM A MISCIBLE POLYMER BLEND

摘要：

Introduction It is generally accepted that the presence of molecular connections between different crystallites, namely, tie molecules, takes the key role in determining the mechanical performance of semicrystalline polymers. Although the concentration of tie molecules can be adjusted by changing the molecular structure and/or varying the crystallization conditions, the polymer crystals with very few tie molecules are difficult to prepare from melt for high molecular polymers due to the molecular entanglement in the bulk state. In this work, we try to change the density of inter-crystalline tie molecules in a semicrystalline polymer via crystallization from a miscible blend.
