The crystallization and melting behavior of PBS was studied in detail [23, 24, 26], It is well know that many semicrystalline polymers, including flexible polymers (such as PBS) and semistiff
polymers, display multiple endothermic peaks in the DSC thermogram [24, 26], Figure 2 shows the DSC results obtained in different cooling/heating cycles of our sample.
Most of them feature elastic flexible tip and stiff or semistiff
I bend end wires of 4' x 4' panels of the (semistiff
) fence over 3 1/2 'x 4' frames made from recycled building lumber or inexpensive 2" x 2" x 8' partition studs.
In the empty morning hours I am getting home from someplace on the subway, and the two men across the aisle from me--one of them wears a shirt with purple-flower design and semistiff
collar--study me with a too close attention, so that I get up and move into another car, knowing that they know that I suspect them.
