In this study, we synthesized two main chain–type block copolymers featuring hydrogen bond donor and acceptor segments through atom transfer radical polymerization (ATRP) using a bifunctionalized polyhedral oligomeric silsesquioxane (POSS) nanoparticle as the initiator. Hydrosilylation of vinylbenzyl chloride at the two corners of a double-decker silsesquioxane (DDSQ) provided the bifunctionalized benzyl chloride initiator VBC-DDSQ-VBC, which we applied as a platform to prepare a main chain–type polystyrene homopolymer (PS-DDSQ-PS), the diblock copolymer poly(styrene–b–4-vinylpyridine) (P4VP-b-PS-DDSQ-PS-b-P4VP), and the diblock copolymer poly(styrene–b–tert-butoxystyrene) (PtBuOS-b-PS-DDSQ-PS-b-PtBuOS) through sequential ATRP. Selective hydrolysis of the tert-butoxyl units of PtBuOS-b-PS-DDSQ-PS-b-PtBuOS yielded the strongly hydrogen bonding diblock copolymer poly (styrene-b-vinylphenol) (PVPh-b-PS-DDSQ-PS-b-PVPh). We used Fourier transfer infrared spectroscopy, nuclear magnetic resonance spectroscopy, size exclusion chromatography, differential scanning calorimetry, mass-analyzed laser desorption ionization mass spectrometry, and transmission electron microscopy to investigate the chemical structures, thermal behavior, and self-assembled nanostructures formed by these main chain–type block copolymers based on DDSQ.

Oligomeric Silsesquioxane

In this work, octa(3-aminopropyl)polyhedral oligomeric silsesquioxane (Oap-POSS) [(NH2CH2CH2CH2)8Si8O12] was synthesized through hydrolytic condensation of (3-aminopropyl)triethoxysilane, and incorporated into epoxy resin (EP) cured with methyl hexahydrophthalic anhydride (MHHPA) to offer a series of novel POSS/EP nanocomposites. The microstructure, thermal stabilities, electric insulation and dielectric behaviors of the epoxy nanocomposites were studied. The results showed that the thermal stability and dielectric property of the POSS/EP increases with the incorporation of Oap-POSS into EP.
