We recently found that side chain crystalline polymer (SCCP), constructed with a long alkane side-chain (more than 10 carbon atoms) monomer (LASM) shows very strong interaction between polyethylene (PE) only by the van der Waals interaction. By using this supramolecular interaction, the side chain crystalline block co-polymer (SCCBC) that was constructed with LASM and functional monomer can act as a chemical surface modifier of PE.<br/>We investigated crystal structure of SCCBC and found it has a very similar crystalline structure of PE (110). We also found the SCCBC makes co-crystal with small molecular weight PE (Wax). This co-crystal shows higher melting point than wax.<br/>Addition to that, we had calculated molecular dynamic simulation between SCCP and PE, and from these investigation, SCCP unit of SCCBC is thought to form a quasi-crystalline structure and this new interaction can be named as crystalline supramolecular interaction.
