Abstract
A number of polydimethylsiloxanes modified with long-chain hydrocarbon substituents with ester or benzylamide terminal groups was synthesized by hydrosilylation and polymeranalogous reactions. The copolymers were characterized by 1H NMR spectroscopy, gel permeation chromatography, and differential scanning calorimetry. The influence of the type and content of modifying substituents on the low-temperature and rheological properties of the copolymers was established and indicates an increased level of intermolecular interactions in the synthesized copolymers compared to PDMS.
