Role of Side-Chain Length on Gas Transport of Co2/Ch4 Mixtures in Polymers with Side-Chain Porosity
Journal of Membrane Science, 2022Polymers of intrinsic microporosity (PIMs) are traditionally formed from ladder backbones, but recent synthetic advances have allowed for the formation of non-traditional PIMs using a poly(ladder) motif, whereby rigid PIM-like sidechains are appended onto more flexible backbones.

Effect of side‐chain length on the electrospinning of perfluorosulfonic acid ionomers
Journal of Polymer Science Part A: Polymer Chemistry, 2012AbstractThe effect of the side‐chain length (short side chain and long side chain, SSC and LSC, respectively) of perfluorosulfonic acid (PFSA) ionomers on the properties of nanofibers obtained by electrospinning ionomer dispersions in high dielectric constant liquids has been investigated with a view to obtaining electrospun webs as components of fuel ...

Conformation of Cylindrical Brushes in Solution: Effect of Side Chain Length
Macromolecules, 2006The conformation of cylindrical brush polymers with a polymethacrylate main and polystyrene side chains (6 ≤ ≤ 33, with the number-average degree of polymerization of the side chains) were studied by combined light and small-angle neutron scattering experiments. The results reveal that the main chain stiffness expressed in terms of the Kuhn statistical

Die Makromolekulare Chemie, 1985
AbstractA series of soluble polymers was prepared by copolymerization of the 4‐nitrophenol ester of N‐methacryloylated ω‐amino acids (1a – i), of N‐methacryloyldiglycine (2b), of 6‐(N‐methacryloylglycylamino)‐ and of 6‐(N‐methacryloylglycylglycylamino)hexanoic acid (3a and 3b) with N‐(2‐hydroxypropyl)methacrylamide (HPMA).

Alkylfurans: Effects of Alkyl Side-Chain Length on Insecticidal Activity
Journal of Natural Products, 1998The insecticidal activity of five alkylfurans against the generalist insect herbivore beet armyworm, Spodoptera exigua, was examined. Two naturally occurring compounds, the avocadofurans 2-(pentadecyl)furan (1) and 2-(heptadecyl)furan (2), previously isolated from specialized avocado idioblast oil cells, and three homologues, 2-(tetradecyl)furan (3), 2-

The effect of isoprenoid side chain length of ubiquinone on life span
Medical Hypotheses, 2003The isoprenoid side chain length of ubiquinone (Q) can have an effect on the life span of mammals. The short living mouse and rat have Q(9), while primates have Q(10) as the major form. Ubiquinones (Qs) having longer hydrophobic tail are likely more imbedded in the mitochondrial inner membrane than the ones having shorter tails.

Influence of side-chain length on phospholipid ordering in two dimensions
Chemistry and Physics of Lipids, 1998Abstract Phosphoethanolamines (PE) with a 2-branched hexadecanoyl chain (ethyl, butyl and tetradecyl) at the sn-1 position of the glycerol backbone and an unbranched hexadecyl residue at the sn-2 position have been synthesised. They form stable monolayers at the air/water interface.

CHIRAL LIQUID CRYSTALLINE SIDE-CHAIN POLYMERS: EFFECTS OF SIDE-CHAIN LENGTH ON PHYSICAL PROPERTIES
Ferroelectrics, 1996Abstract The synthesis of a series of side-chain liquid crystalline siloxane copolymers is reported, and comparative studies of physical properties of members with different side-chain length have been attempted. Measurements of ferroelectricity and relaxation times aimed at studying structure-property relationships for the longer side-chain members ...
