“…The grafted AMPS monomer acts as a nucleation agent, which improved the crystallization capability of LLDPE molecular chains, and LLDPE molecular chains might crystallize at higher temperature. This was also observed by other authors (27,28) who reported a nucleation effect of grafted monomer on the crystallization of polyolefins. Table 3 lists the tensile strength, elongation at break and Young's modulus for samples of LLDPE and LLDPEg-AMPS with different monomer concentration.…”

Linear low density polyethylene (LLDPE) was functionalized with 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) by using β-ray pre-irradiation in air in a twin-screw extruder. Fourier-transformed infrared spectroscopy (FT-IR) and electron spectroscopy for chemical analysis (ESCA) were used to characterize the formation of LLDPE-g-AMPS copolymers. The content of AMPS in LLDPE-g-AMPS was determined by using element analysis instrument. The effects of concentrations of monomer, reaction temperature and pre-irradiation dose on degree of grafting were investigated. The critical surface tension of LLDPE-g-AMPS was measured by using contact angle method. The influences of the degree of grafting on crystallization properties were studied by using DSC. Compared with neat LLDPE, the crystallization temperature increased about 4 • C, and crystallinity decreased with increasing degree of grafting. Crystallization rates of grafted LLDPE were faster than that of plain LLDPE at the same crystallization temperature.

“…For this reason, intensive work has been done regarding the chemical modification of this polyolefin. [4][5][6][12][13][14]26] Bisphenol-A polycarbonate (PC) is a widely used engineering polymer because of its unique combination of properties. This high-performance thermoplastic is basically amorphous and, therefore, transparent.…”

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.

“…Polymer/polymer adhesion is of use in many presentday industrial applications and of the various techniques enabling such assembly, much promise is shown by that of grafting a chemical species at the interface [1][2][3]. Certain applications require ''composite'' polymer structures consisting of multilayer materials which present better overall performance than the individual components on their own.…”
