- Brief description
- Banded spherulites in a blend of polyethtylenes
- Keywords
- alignment, blend
, polyethylene (PE), polymer , quenching , sheaf, spherulite - Categories
- Polymer
- System
- Polyethylene (PE)
- Composition
- LPE:BPE 1:3
- Standard codes
- Reaction
- Processing
- Blend (1:3) of linear and lightly branched polyethylenes. The blend was quenched from 163 degrees C
- Applications
- Polymer blends are commercially important materials. Blending very similar polymers can produce materials with improved properties.
- Sample preparation
- Technique
- Transmission electron microscopy (TEM)
- Length bar
- 200 nm
- Further information
- A replica of a 1:3 blend of linear with lightly branched (BPE has 26 branched per 1000 backbone carbon atoms) polyethylenes after quenching from a mixed melt. The lamellae are of a single type, all of the same thickness. In this case the lamellae are arranged in the familiar banded spherulites.
