Polyamide 66 (PA66) has been complexed with the Lewis acid GaCl 3 for the purpose of disrupting the interchain hydrogen bonded network. FTIR and 13 C-NMR observations indicate that Ga metal cations form a 1:1 complex with the carbonyl oxygens of the PA66 amide groups. PA66-GaCl 3 films are amorphous and rubbery with a single relaxation, attributable to the glass transition...
3-(Trimethoxysilyl)-propyldimethyloctadecyl ammonium chloride (AEM 5700) is a trifunctional monomer that can be polymerized under acidic conditions at temperatures greater than 100 o C. Under such conditions, coatings based on AEM 5700 formed on PET substrates are relatively hydrophobic and exhibit rewetting times higher than 100 min. Hydrophilic coatings exhibiting a rewetting time of 2.8...
Ternary blends of polypropylene (PP), nylon 6 (N6) and polypropylene grafted with maleic anhydride (PP/N6/PP-g-MAH) as compatibilizer with up to 50wt% of N6 were investigated. PP-g-MAH content was varied from 2.5 to 10%. Blends of the two polymers PP/N6 (80/20) without the compatibilizer were also prepared using an internal batch mixer and studied. The ternary blends showed different rheological properties...
