WebA polymer's molecular structure strongly affects crystallinity. If it's regular and orderly, highly symmetrical, it will pack into crystals more easily. In a way, the molecules want to get next to each other in crystalline domains. If the molecular structure is not highly regular and symmetrical, it won't.
