The competition between self-seeding and specific nucleation in crystallization of long-chain branched polypropylene
The main purpose of this work is to present the effect of long-chain branching and specific α-nucleation on the optical properties, crystallization and supermolecular structure of polypropylene (PP). Commercially available α-nucleating/clarifying agent 1,3;2,4-bis(3,4-dimethylbenzylidene)sorbitol (M...

| description | The
main purpose of this work is to present the effect of long-chain branching and
specific α-nucleation on the optical properties, crystallization and
supermolecular structure of polypropylene (PP). Commercially available α-nucleating/clarifying
agent 1,3;2,4-bis(3,4-dimethylbenzylidene)sorbitol (Millad 3988) was mixed into
linear PP and long-chain branched PP (LCB-PP) in the concentration of 0.2 wt%.
For the study of polymorphic composition, crystallinity, and crystallization process
under isothermal conditions in the temperature range of 130–150 °C,
differential scanning calorimetry and wide-angle X-ray scattering were used.
Although the used nucleating/clarifying agent appears to have a slight effect
on the optical properties of long-chain branched polypropylene, it does not
appear to affect the crystallization kinetics significantly. LCB-PP exhibited
self-nucleation, favored over nucleation by a specific nucleating agent. |
