Usage

General Description

Aminopropyllsobutyl POSS is a type of polyhedral oligomeric silsesquioxane (POSS) that contains both amine and alkyl groups. It is commonly used as a nanofiller in polymer composites to improve mechanical and thermal properties. Aminopropyllsobutyl POSS has a unique cage-like structure that provides enhanced chemical and thermal stability, making it suitable for a wide range of applications in coatings, adhesives, and aerospace materials. Its compatibility with various polymers allows for improved dispersion and bonding at the molecular level, resulting in enhanced performance and durability of composite materials. Overall, Aminopropyllsobutyl POSS plays a vital role in advancing the field of nanotechnology and engineering materials.

Synthesis, thermal stability and photoresponsive behaviors of azobenzene-tethered polyhedral oligomeric silsesquioxanes

A series of azobenzene-tethered polyhedral oligomeric silsesquioxane (POSS) derivatives, i.e. monoazobenzene-substituted POSS (MonoAzo-POSS), bisazobenzene-substituted POSS (BisAzo-POSS) and triazobenzene-substituted POSS (TriAzo-POSS), were synthesized through the amidation acidylation of aminopropylisobutyl POSS and benzoic acid derivatives (AzoMs) with one, two and three azobenzene groups (AzoM1, AzoM2 and AzoM3). Their structures were characterized by FT-IR, 1H NMR, 13C NMR and mass spectra, and their thermal stability and photoresponsive behaviors in DMF solutions were evaluated with TGA, XRD and UV-vis spectra, respectively. The results indicated that the thermal stability and photoisomerization of azobenzenes could be effectively controlled by their molecular structure. In MonoAzo-POSS, the large steric hindrance of POSS destroys the molecular ordering and limits the molecular packing, contributing to its poor thermal stability. And the low molecular ordering of MonoAzo-POSS offers an azo group with large free space, and its trans-cis photoisomerization rate increases accordingly. But, in BisAzo-POSS and TriAzo-POSS, the incorporation of POSS units does not impact on the regularity of azobenzenes obviously, and the hindrance effect of nanosize POSS on the molecular motion plays a primary role in increasing their high thermal stability. Their photoisomerization rates decrease due to the steric hindrance of POSS and the unfolding structure of the azo moieties in BisAzo-POSS and TriAzo-POSS.

NCO-containing compounds with covalent bound polyhedral oligomeric silicon-oxygen clusters

Functional isocyanate compounds obtained by reacting polyisocyanates with polyhedral, oligomeric silicon-oxygen cluster compounds containing groups which react with isocyanate, so that 1-20 mol% of the original isocyanate groups undergo conversion (or 80-99 mol% if a blocking agent is used). NCO-containing compounds (I) with covalently-bonded, polyhedral, oligomeric silicon-oxygen cluster units (POSO) formed by the reaction of (A) aromatic, aliphatic and/or cycloaliphatic polyisocyanate(s) with an NCO functionality of 2-6 with (B) 0.001-20.0 wt.% POSO units containing NCO-reactive functional groups, with 1-20 mol% conversion based on originally-present free NCO groups and optionally (C) a blocking agent, with 80-99 mol% conversion of NCO groups. Independent claims are also included for: (1) paint containing (I) as crosslinker, with at least one polyol component (2) coatings obtained with this paint.
