Synthesis of polysilanes bearing pendant carbosilyl groups and 29Si-NMR probe on the tacticity using side chain silicon atoms
New functional polysilanes [R2R1Si(CH2)2SiH]n (R=Me, R1=H (1); R=R1=Et (2); R=Me, R1=Ph (3)) bearing carbosilyl side chains have been synthesized by catalytic dehydropolymerization of precursor carbosilanes R2R1SiCH2CH2SiH3 ...
Structural investigations of poly(methyl methacrylate) by two-dimensional NMR
In the present paper a comprehensive microstructure analysis of PMMA based on the combination of one-dimensional and two-dimensional (TOCSY, HSQC, and HMBC) NMR experiments is reported. To resolve complex resonance ...
