Surface Modification of Polyethylene Films via Bromination:  Reactions of Brominated Polyethylene with Aromatic Thiolate Compounds

Precision Ethylene/Vinyl Bromide Polymers

“…[19] Importantly, these spectra suggest, in accord with our previous work on PE19Br, that these three precise E/VB polymers possess a triclinic rather than an orthorhombic crystal structure based on the absence of doublets at 1463-1472 cm . [12,17] The proposed triclinic structure is also supported by differential scanning calorimetry (DSC) as well ( Figure 2).…”

Manipulating interactions between functional colloidal particles and polyethylene surfaces using interfacial engineering

“…The spectrum also showed weaker absorption bands at 1472 and 1465 cm À1 (CH 2 scissoring), at 1379 cm À1 (symmetric CH 3 bending) and at 1008-1127 cm À1 (indicative of some contaminations by oxygen-containing molecules). Similar results for unmodified polyethylene films have been reported in previous studies [11,19,20]. The modification of the PE film surface by UV-ozone treatment led to the appearance of a new absorption band at 1700-1720 cm À1 , which can be attributed to C@O stretching vibration in COOH carboxyl groups [21].…”

“…Polyethylene (PE) is a synthetic polymer that is commonly used as a food packaging material, e.g., in the plastic bottles used to contain many soft drinks and fortified waters [10]. PE has a relatively high surface hydrophobicity and smoothness, which normally inhibits the binding of hydrophilic components that come into contact with it [11]. Nevertheless, the surface characteristics of PE can be 0021-9797/$ -see front matter Ó 2011 Elsevier Inc. All rights reserved.…”

Ring opening polymerization of 3-semifluoro- and 3-bromomethyloxetanes to poly(2,2-substituted-1,3-propylene oxide) telechelics for soft blocks in polyurethanes

“…The SMA approach is simpler than plasma [2,3], plasma followed by grafting [4][5][6], or chemical processes [7][8][9] since in favorable cases there are no post-processing steps.…”
