“…Some desirable properties such as biocompatibility, ion-exchange, and thermo-sensitivity can be obtained on many polymer surfaces by the grafting method. Ionizing irradiation, ultraviolet light, plasma and chemical initiators are useful methods for grafting co-polymerization [1][2][3][4]. Polymeric materials based on commodity thermoplastics are attractive, not only for their low cost, but also for their technical performance, versatility of processingtransformation and simplicity of recycling [5].…”

Low-density polyethylene membranes (LDPEs) were modified by the mutual grafting of 2-(dimethylamino) ethyl methacrylate (DMAEMA) and poly(ethylene glycol) methyl ether methacrylate (PEGMEMA) using a direct method with gamma-rays. The effects of absorbed dose and monomer concentration were determined. The grafted samples were confirmed by Fourier transform infrared spectroscopy, thermal properties were analyzed by differential scanning calorimetry and thermogravimetric analysis, and the stimuli-responsive behavior and critical pH point were studied by swelling determination and measurement of the contact angle in water. pH-and thermo-responsive membranes of LDPE-g-DMAEMA/PEGMEMA exhibited a low critical solution temperature of 40 • C and critical pH point around 7.5.

“…The experimental procedure of grafting of poly(acryloyl chloride) was reported previously. 12 The PP film and acryloyl chloride (70%) in toluene were placed in a Pyrex ampoule, and the ampoule was sealed off in vacuum after degassing by repeated freeze/thaw cycles, and irradiated at a dose rate of 4 kGy/h (Direct method). The irradiation was also carried out for the PP film but in the vapor of acryloyl chloride (Vapor phase method).…”

“…The present authors have been studying the ␥-ray-induced graft polymerization of functional monomers onto common polymer films, and have previously reported the methods of grafting acryloyl chloride onto hydrocarbon polymers. 12 In this work, a polypropylene film was grafted with poly(acryloyl chloride), which was then converted to polyacrylate containing Disperse Red 1, which is commonly available at a relatively low cost. The preparation, characterization, and some properties of the grafted films are reported in this article.…”

Polypropylene (PP) films were grafted with acryloyl chloride by ␥-irradiation, and the grafted films were reacted with an azo dye, Disperse Red 1. The films were characterized by X-ray diffraction, scanning electron microscopy, atomic force microscopy, and differential scanning calorimetry. It was found that the grafting takes place first on the film surface, and with increase in the radiation dose the grafting penetrated inside of the film, decreasing the crystallinity of the PP film. The surface of the films was homogeneous, and a mesophase was observed for the film grafted with the dye through a polarized optical microscope. The dye underwent trans to cis photoreaction, whereby the red films became colorless by the irradiation of UV light at room temperature, although the color was recovered on standing, and more quickly when heated.

“…[4] In this sense, the study of the effects of gamma rays in polymers [12][13][14] has allowed proposing grafting by gamma radiation as a promising method for the insertion of functional groups into different polymer matrices, considering its advantages such as the high radical generation rate with the additional exclusion of chemical initiator agents. [15][16][17] The study of grafting by gamma irradiation could be similar to other methodologies used, where the grafting degree is related to monomer and initiator concentration, chemical nature of the substrate, with the additional consideration of the radiation conditions. However, it is well known that exposition to g-rays can induce polymer modifications [18][19] Therefore, the selection of appropriate grafting conditions is an important task.…”

Summary: The grafting of diethyl maleate onto low-density polyethylene using gamma irradiation as initiator has been evaluated. The grafting degree was estimated by FTIR and with the use of a calibration curve. The functionalized polymers were characterized by DSC, MFI, SSA and GPC. An increase in the grafting degree with the radiation dose and the concentration of the functional monomer was found. Branching seemed to be the preferential reaction induced by radiation, causing an increase in average molecular weights with the consequently reduction of melt flow index values. The molecular segregation induced by the calorimetric treatment showed that grafting occurs preferentially through secondary carbon sequences.
