“…In particular, exposure to UV-light first leads to a decomposition of the photoinitiator which generates radicals, reacting in a second step with the acrylic functions of the monomer. As a result, the photopolymerized system has been elaborated essentially through these reactive functions, and cross-linking generally occurs at the end of the polymerization process via a chain termination reaction [24][25][26]. EB-curing proceeds without any initiator and the radiation creates radicals not only on the reactive acrylic functions but also randomly on the medium.…”

The thermomechanical properties of electron beam (EB) and ultraviolet (UV) cured TPGDA (tripropyleneglycol diacrylate)=liquid crystal (LC) blends were the subject of static and dynamic analysis. In the glassy region of the LC, a very strong temperature dependence on the polymer storage modulus was found for EB-cured networks in the range of compositions 40-60 weight.-% of LC. Above the LC glass transition temperature (T g ), the LC behaves like a plasticizing agent. Below T g of the LC, the LC reinforces the polymer. In the case of the UV-cured system, the effect of plasticizing of the LC remains dominant from À100 to þ100 C.

“…The γ radiation has been used to graft methacrylic acid onto polypropylene,16 acrylonitrile onto natural rubber,17 and hydroxyethyl methacrylate (HEMA) onto EPDM 18. EB radiation has been used for the polymerization of acrylate‐based monomers and modification of elastomers using polyfunctional acrylates 19–21. This investigation reports successful grafting of methyl methacrylate (MMA) and butyl acrylate (BA) on IIR by using EB radiation.…”

Being nonpolar in nature, butyl rubber (IIR) has poor compatibility toward polar polymers and fillers. It can be improved by grafting polar substrates on the butyl elastomer. Radiation-induced polymer processing is getting increasing interest, as it leads to new and improved polymers with desirable and interesting properties. In this investigation, electron beam radiation has been used to graft methyl methacrylate (MMA) and butyl acrylate (BA) on IIR. This process has several advantages over conventional grafting processes such as cationic polymerization (which needs very low temperature and stringent reaction conditions) and solution radical polymerization (which often needs solvent removal and recycling). The grafted polymers were characterized by using 1 H NMR, IR, TGA, and SEM analysis. The degree of grafting increases with a decrease in irradiation dose as well as with an increase in monomer concentration. It was observed that there was a decrease in intrinsic viscosity in irradiated IIR samples, indicating the chain scission.

Effect of electron beam on mechanical, thermal, and morphological properties of ethylene methyl acrylate copolymer, grade Elvaloy 1335 has been investigated. The copolymer was subjected to varying doses of electron beam radiation with different proportion of the sensitizer trimethylolpropane trimethacrylate (TMPTMA). It was observed that with increase in electron beam dose, the physicomechanical properties of the crosslinked copolymer improve, reaches an optimum level and subsequently deteriorates. The thermal properties as envisaged from thermogravimetric analysis and differential scanning calorimetric studies revealed stability of the crosslinked irradiated samples over that of the unirradiated ones. The thermal stability was also found to attain the maximum at the same level of radiation and sensitizer. The morphological studies showed consistency with the mechanical properties. Based on the overall study, it may be concluded that ethylene methyl acrylate copolymer with 1 phr TMPTMA at 60 kGy radiation dose is the optimum condition within the range studied in this investigation.
