This could be because of flexible nature of the films formed because of the presence of long aliphatic chains present in dimer fatty acid resulting in free volume available between adjacent chains.
2]- represents the linear aliphatic chain present in structure.
The modern kerogen models consider it to be a complicated three-dimensional polymer, which consists of aromatic, hydroaromatic, and heterocyclic structures (clusters) connected with each other by aliphatic chains and containing various functional groups (hydroxyl, methyl, carboxyl, etc.
Alkylated phenolic structures, mainly alkylresorcinols and condensed alicyclic rings connected by aliphatic chains, underlie the molecular model of kukersite kerogen elaborated in  on the basis of spectroscopic investigations.
US 6,248,315 B1: Procter & Gamble has earned a patent for hair styling shampoo compositions that contain a synthetic surfactant, dispersed latex polymer particles, water-soluble cationic polymer, an organic oil with aliphatic chains
The esterified product molecule is composed of both the unreacted hydroxyl groups and one or two long aliphatic chains
The juxtaposition of both spectra shows that the IR spectrum for shale oil obtained by pyrolysis with water vapour clearly shows dominant presence of long aliphatic chains
(a band at 720 [cm.
In a previous article (24) we reported the formation of microstrucured thermosets with dispersed HBP particles of about 1 to 2 [micro]m when Boltom H30 esterified with long aliphatic chains
was added as modifiers of diglycidylether of bisphenol A (DGEBA) cured by Yb[(OTf).
2]- and CH- groups in aliphatic chains
and aromatic ring systems of different degree of condensation and substitution.
The decomposition of DGTH3 film can be divided into three parts: the degradation of DOPO groups, the degradation of amide groups and ester groups, and the degradation of aliphatic chains
Coating thickness measurements made by XPS suggest that the aliphatic chains
of low molar mass fatty acids lie predominantly perpendicular to the filler surface, following coating, a result that carries implications regarding the definition of 'monolayer,' in these systems.
2] filler surface, the aliphatic chains
are of sufficient length and are of identical chemical structure to enable physical interaction with the MDPE matrix.
