The structure of polyethylene, as revealed by solvent extraction
- 68 Downloads
When high density polyethylene (HDPE) is crystallized from the melt at low super-cooling, quenched, and then treated with xylene at ∼100° C, part of it dissolves. The remaining part is that which crystallized at the low supercooling. Scanning electron microscopy of the spherulite boundaries in the treated sample shows very clearly the open lamellar structure which was the growth front at the time of quenching.
