Skin - core structure It is well known that injection - molding of unfilled polymers
results in a skin - core structure ... This region , composed of cylindrites ( row
structures due to shearing ) , was not present in plaques molded from PBT a
decade ...

The crystallinity profile shows a general increase towards the center of the
molded specimen ( e . g . , ( 14 , 16 ] ) . The highest overall crystallinity and the
largest spherulites can be found in the midcore region . Increasing the mold
temperature ...

Figure 10 clearly shows the K , deterioration achieved by wet molding of PET
without ( MI ) ... modifier ( MII ) as a function of Mw . Wet molding induces
hydrolytic cleavage of the ester bonds , thus resulting in decreased molecular
weight .
