What is The influence of hydrogen bonding on the preparation and mechanical properties of PS-diblock copolymer blends about?
## Abstract In this article, the preparation of nanosized core‐shell particles to induce ductility in polystyrene (PS) is described. FTIR spectroscopy, solid‐state NMR spectroscopy, and DSC were used to examine the extent of miscibility of PS and poly(butylacrylate)‐__b__‐polyolefin diblock copolymers in a blend in which PS was chemically modified by copolymerization with 0.5–5 mol % of __p__‐(hexafluoro‐2‐hydroxy isopropyl) styrene (HFS). Hydrogen bonding between the hydroxyl‐groups and the carbonyl‐groups of polybutylacrylate enhanced the miscibility and lead to randomly distributed polyolefin particles surrounded by a homogeneous PBA/PS matrix. Morphological parameters such as the size of the dispersed phase or extent of interpenetration between the components are controllable simply by changing the amount of interacting groups in the blend. The mechanical properties of the prepared blends were also studied. The intrinsic deformation behavior was investigated by compression tests, whereas the microscopic mode of deformation was studied by time‐resolved small‐angle X‐ray scattering. It was shown that the macroscopic strain at break depends to a large extent on the diblock copolym
