Functionalized polybut-1-ene, obtained by mixing 100 parts by weight of solid phase functionalized olefinic polymers with a portion of grafted carboxyl monomer, 0.1-60 parts by weight of at least a functional monomer or at least a functional monomer containing monomer mixture, and 0.01-20 parts...
6(e). So far, the most common strategy used to induce mechano-responsiveness in mechanophores relies on the presence of weakened bonds, isomerizable bonds or strained rings keen to react once a sufficiently high mechanical stress is transmitted to the moieties through the polymer chains. Thanks...

1.A process for preparing functional group-containing olefinic compounds comprising the steps of:(a) reacting (1) at least one alkylidene phosphorane comprising an alkylidene moiety and three other moieties bonded to its phosphorus atom, said alkylidene moiety optionally comprising one or more carbon ...
These structural studies were based on the oxi- dative degradation of carotenoids with KMnO4, and struc- tures were analyzed using elemental analysis. In the 1950s, the Zechmeister group studied E/Z (cis–trans) isomeriza- tion of carotenoids. In the 1960s, the Weedon group and Liaaen...
We used a similar bisdiene 29b and bisalkene 33 to construct ladder polymer 34.79,80 In our approach, a 1:1 mixture of the syn-isomer of bisalkene 33 and its anti-isomer that would form a more extended D–A adduct were used to suppress the possible formation of small cyclic products....
using HP-chiral (20% β-cyclodextrin, Supplementary Table S4 program 4) capillary column revealed that SaSQS1 produces a racemic mixture of linalool and α-terpineol (Supplementary Fig. S33), whereas SaBS forms a single isomer of α-terpineol (Supplementary Fig. S34). For the functional ...
Keywords: functional gels; hydrogels; microgels; hybrid microgels; stimuli-responsive; shape memory hydrogels; self-healing gels 1. Introduction Gels have pervaded our everyday life in a variety of forms. The wet soft solids that we encounter in the form of commercial products such as soap, ...
The δ-damascone was grafted via a 2-cysteamine linker by 1,4-addition of the thiol group to the enone double bond of the damascone, followed by the nucleophilic ring opening of the maleic anhydride unit by the amino group. Furthermore, we were interested in particular in how the molar ...
Functional groups of atoms remain embedded within the structure of an organic molecule and impart specific chemical properties to the compound. The bond connectivity of the atoms in a functional group determines their chemical nature and reactivity. ...
