“…[15][16][17][18][19][20] We already reported the crosslinking reaction and biodegradability of itaconateunit-incorporated poly(butylene succinate) (PBSI) prepared by the reaction of SA, BD, and itaconic acid (IA), 21 all of which are inexpensive and can be derived from biomass resources. 22 The itaconate C¼ ¼C bond of PBSI can be reacted with acryl groups incorporated into polysilsesquioxanes.…”

Itaconate-unit-containing poly(butylene succinate) (PBSI) was synthesized by the reaction of 1,4-butanediol, succinic acid, and itaconic acid in a molar ratio of 2.0 : 1.0 : 1.0, and the obtained PBSI was reacted with methacryl-group-substituted polysilsesquioxane (ME-PSQ) in the presence of benzoyl peroxide (BPO) at 1308C to produce PBSI/ME-PSQ hybrid composites. The thermal and dynamic mechanical properties of the PBSI/ ME-PSQ hybrid composites were investigated in comparison with those of PBSI cured at 1308C in the presence of BPO. As a result, the hybrid composites showed a much higher thermal degradation temperature and storage modulus in the rubbery state than the cured PBSI (C-PBSI). The thermal degradation temperature and storage modulus of the hybrid composites increased with increasing ME-PSQ content. The glass-transition temperature, measured by dynamic mechanical analysis of the hybrid composites, somewhat increased with increasing ME-PSQ content. However, the glass-transition temperatures of all the hybrid composites were lower than that of C-PBSI. Although the IR absorption peak related to C¼ ¼C groups was not detected for C-PBSI, some olefinic absorption peaks remained for all the hybrid composites.

“…Schmalz and Reinicke designed to replace the terminal halogen of the ATRP-derived polymer with azide and the subsequent click reaction by alkynyl compounds, which confirmed effectively. 29 In this article, POSS-(Cl) 8 with the ability to initiate polymerizations [30][31][32] was firstly synthesized by hydrolysis and condensation of 3-chloropropyl trimethoxysilane as reported. 33 Using it as ATRP initiator, star-shaped chlorine-terminated POSS-methacrylate polymers (POSS-(PXMA-Cl) 8 ) were synthesized.…”

Star-shaped polyhedral oligomeric silsesquioxane (POSS)-methacrylate hybrid copolymers with phenyl-triazole as terminal groups had been designed and synthesized via sequential atom transfer radical polymerization (ATRP), azidation, and phenylacetylene-terminated procedures, and the hybrid copolymers here could be denoted as POSS-(PXMA-Pytl) 8 , where X can be M, B, L, and S, represented four different methacrylate monomers, such as methacrylate (MMA), butyl methacrylate (BMA), lauryl methacrylate (LMA), and stearyl methacrylate (SMA), respectively. Thermal gravimetric analysis (TGA) and in situ Fourier transform infrared spectroscopy (FTIR) were applied for studying the thermal stability and degradation mechanism, and it was found that all of the POSS-(PXMA-Cl) 8 and POSS-(PXMA-Pytl) 8 copolymers exhibited excellent thermal stabilities, which had great potential in heat-resistant material application. Different tendencies of decomposition temperatures at 5% and 10% weight loss (T 5 and T 10 ) dependent on the side-chain length and terminal group species were investigated respectively. The longer alkyl side chains of the monomers, the lower thermal stabilities, and enhanced T 5 and T 10 were also shown with the introduction of phenyl-triazole groups instead of chlorine groups.

Polyhedral oligomeric silsesquioxane (POSS) is an important inorganic-organic hybrid material with a threedimensional structure. Polyurethane (PU) is a widely applied polymer that has versatile properties with the change of two phase structure. When POSS is incorporated into PU by physical or chemical methods, many properties can be greatly improved, such as mechanical properties, thermal stability, biodegradation resistance, and water resistance. This paper reviews the recent progress in preparation, structure, and performance of POSS-modified polyurethane from the viewpoint of physical blending and chemical modification.
