The first LDPE/HDPE blends were patented by du Pont de Nemours before Z-N polymers became available (Roedel 1961). The blend comprised an experimental HOPE (p = 0.939-1.096 g mL Tm 120 °C) obtained by polymerizing C2 in its own medium at T 0 °C and P 31 MPa, using, e.g., a hydroxy-cyclohexyl-L-hydroperoxide catalyzed by ferrous chloride tetrahydrate. The blend showed 50 % moisture permeabDity of that by LDPE. In 1958 Phillips Petroleum patented PE/PE blends, either cross-linked in electron accelerator or not (Canterino and Martinovich 1963 Nelson 1964). Mitsubishi disclosed PO blends comprising vinyl-trimethoxysUane-grafted polyolefin (PP, LDPE, EPR, or EVAc) and ethylene-acryloyloxy tetramethylpiperidine copolymer. These water-cross-linkable resins were used for the manufacture of weather-resistant cross-linked PO pipes in outdoor applications (Ohnishi and Fukuda 1993). Thermally reversible cross-links (based on ionic interaction between maleated- and glycidyl methacrylate-grafted polyolefins) were also proposed (Okada 1994 Okada and Masuyama 1994). 

Polypropylene (homopolymer precursor), Hivalloy reactor product (PP-g-PS), and functionalized Hivalloy [PP-g-PS(S-Co-GMA)] glycidyl methacrylate graft were blended with a recycled PET material obtained from Star Plastics in pelletized form. The materials were bag blended (Table 5.1) and stabilized with 0.1% Irganox 1010 and PEPQ based on total batch weight.

Mashita et al [29] described interchain copolymer formation in compatibilized PP blends with PP-g-MA, PET, and glycidyl methacrylate grafted ethylene vinyl acetate (EVAc-g-GMA). The compatibilized blends had markedly higher impact strength and tensile properties than blends with either non-fimctionalized PP or without EVAc-g-GMA.

Hoffman and his coworkers have done a lot of work on the apphcation of radiation-induced graft polymerization for medical apphcation. The hydrophilic polymers that have been used for radiation-induced grafting are Al-vinyl pyrohdone (NVP), 2-hydroxyethyl methacrylate (HEMA), acrylamide (AAm), acrylic acid (AAc), glycidyl methacrylate (GMA), ethyleneglycol dimethacrylate (EGDMA), and ethyl methacrylate (EMA) onto sihcone rubber were widely smdied.

Figure 14.6 Simplified structure for random ethylene-acrylic ester-glycidyl methacrylate terpolymers which are effective rubber tougheners for PET compounds. The ethylene-acrylic ester segments provide elastomeric properties while the glycidyl methacrylate functionalities enable reactive grafting to the PET matrix via the hydroxyl and carboxyl chain ends of the latter...

Elastomers with reactive end groups such as maleic anhydride (MA) or glycidyl methacrylate (GMA) are preferred for toughening PET. The reason that they are so effective is that they form a graft copolymer by reaction with the PET hydroxyl and carboxyl end groups (as shown below). The graft copolymer then acts as an emulsifier to decrease the interfacial tension and reduce the tendency...
