“…However, no block or graft copolymer was generated at the interface because of the low reactivity of the anhydride with carbonate linkages in multilayer films. The results of T‐Peel test clearly reveal the pendent primary amine groups were necessary to promote adhesion to PC, even though results of peel strength were low as have been seen in other comparable multilayer films 16, 26…”

“…The results of T-Peel test clearly reveal the pendent primary amine groups were necessary to promote adhesion to PC, even though results of peel strength were low as have been seen in other comparable multilayer films. [16,26] Conclusion Maleated PP was amine functionalized in the melt using low molecular weight diamines. A mixed grafting of amide-imide groups was detected in PP using FT-IR and a deconvolution process.…”

“…A way to introduce primary amine groups into PP is by reacting bifunctional compounds and maleic anhydride group grafted in PP 13, 17, 18. The reaction between primary amine diamine and maleic anhydride group is faster and produces amic acid and/or imid bonds, such as has been reported in functionalization of polyethylene11, 16 and styrene/maleic anhydride copolymer (SMA) 11, 19, 20. The effectiveness of amine functionalized PO's has been evaluated in compatibilization of blends of PO's and poly[acrylonitrile‐ co ‐butadiene‐ co ‐(acrylic acid)] (NBR),21, 22 SMA,22 ethylene propylene rubber (EPR),23 ethylene propylene diene monomer (EPDM),24 and thermoplastic polyurethane (TPU) 25…”

Aminated poly(propylene) was prepared by reacting aliphatic primary diamines with maleic‐anhydride‐functionalized poly(propylene) by in situ melt reaction. Around 60–70% of the initial acid groups had reacted to form amide and imide groups as confirmed by the almost complete disappearance of the maleic anhydride peak in FT‐IR spectra. The molecular weight of the diamines had an influence on changes in molecular structure of the PP‐g‐NH2 as a result of secondary reactions such as chain extension and cross‐linking. PP‐g‐NH2 and polycarbonate were pressed into two‐layer films and their adhesion strength was measured. The results showed that PP‐g‐NH2 was a very effective adhesion promoter.

High density polyethylene [HDPE] grafted with 0.13, 0.04 and 1.04 wt% maleic anhydride (abbr.: PEMA) was modified with an excess of a variety of diamines in near critical propane. The resulting amic acid groups were quatitatively imidized to the corresponding imide (PEMI) in the melt. Increasing the percentage maleic anhydride grafted on the HDPE resulted, upon reaction with the diamines, in an increased gel content, due to crosslinking. Three‐layered films were prepared using HDPE film and polyethylene dterephathalate (PET) film as the outer layers and the PEMAs and PEMIs as the inner layer. Adhesion strengths were measured using a T‐peel test. Increasing the bonding temperature resulted in an improved adhesion. The most optimal system for adhesion proved to be HDPE grafted with 0.40 wt% MA and modified with a pendent secondary amine group. For this system the lowest number of reactive amine groups was lost owing to crosslinking reactions, so the highest concentration of amines is available for interactions with the PET film. The absence of extensive HDPE crosslinking in addition implies a better flow of the adhesive layer during lamination. From contact angle measurements, it was observed for all samples that after delamination of the three‐layered system, PET was present on the PE‐surface and PE was present on the PET‐surface.
