Abstract
Because of the presence of supramolecular bonds, the crystallization process of supramolecular pseudoblock copolymers (SPBCP) is more complex in comparison to conventional covalently bonded block copolymers (BCP). Thus, supramolecular binding motives included on the polymer chain-ends display additional dynamic effects as well as possible nuclei for the crystallization. In this article we systematically study nonisothermal crystallization processes in SPBCP’s consisting of a crystallizable poly(e-caprolactone) (PCL) connected via triple hydrogen bonds to either a short alkyl-modified 2,4-diaminotriazine, or bound to a large block of amorphous poly(isobutylene) (PIB). The crystallization of the PCL is studied with both groups acting as supramolecular barriers for the crystallization process, either during nucleation or during crystal growth. A strong influence of the short alkyl-modified 2,4-diaminotriazine barrier on the crystallization temperature of the PCL compared to the control sample devoid of this ...
