Synthesis of photocrosslinkable fluorinated polydimethylsiloxanes: Direct introduction of acrylic pendant groups via hydrosilylation

Photo-Cross-Linked PDMSstar-PEG Hydrogels: Synthesis, Characterization, and Potential Application for Tissue Engineering Scaffolds

“…The lack of cyclic materials is confirmed by GPC of a–c. Si-H terminal groups of a–c were subsequently converted to photo-sensitive methacrylate groups by Pt-catalyzed hydrosilylation of each with allyl methacrylate to yield A–C , respectively 47 . A–C exhibited a slight increase in M w by GPC versus the corresponding a–c due to an apparent small amount of crosslinking, despite our efforts to minimize exposure of A–C to light and to promptly use in hydrogel fabrication and characterization.…”

Synthesis and properties of polysiloxanes containing polyhedral oligomeric silsesquioxane (POSS) and oligo (ethylene oxide) groups in the side chains

“…[30][31][32] Meanwhile, it has also been shown that Markovnikov products could be produced together with anti-Markovnikov products with subtle changes of reaction conditions such as the types of alkenes and catalyst. [33][34][35][36][37] In our case, only anti-Markovnikov product was obtained from the hydrosilylation reactions of allyl-CyPOSS and allyl-EO#.…”

Polysiloxanes containing alkyl side groups: synthesis and mesomorphic behavior

“…In general, hydrosilylation of PMHS using platinum catalysts undergo anti-Markovnikov addition of hydrosilane groups to the carbon-carbon double bonds. [13][14][15] However, subtle differences in the catalyst and reagents afford some degree of Markovnikov addition. 16 In our case, the ratio between propyl (-Si-CH 2 -CH 2 -CH 2 -S-) produced from anti-Markovnikov addition and 1-methyl ethyl (-Si-CHCH 3 -CH 2 -S-) produced from Markovnikov addition is about 1:1 for all nTPs.…”
