“…Because of their advantageous properties, polyolefins, such as PE, PP and PS, are widely used in a number of areas (from industry to everyday life). However, the possibilities of their modification (especially PE and PP) with POSS units can be limited and concern either physical blending (POSS with inert groups) or their initial preparation, i.e., irradiation or temperature initiation to create active sites at the polymer matrix, which are able to be grafted with FG of modifiers (usually via radical mechanism) [12,16]. For PS, it is also likely to functionalize their phenyl ring using, e.g., Friedel-Crafts reaction [17].…”

In this paper we demonstrate a facile and efficient synthesis of monoalkenylsubstituted POSS compounds, i.e., R 7 (Si 8 O 12 )alkenyl and R 7 (Si 8 O 12 )(OSiMe 2 )-alkenyl with a functional alkenyl group of chain length (from vinyl to dec-9-enyl, with or without additional -OSiMe 2 -spacer between the silsesquioxane core and alkenyl moiety) and with five types of inert groups (Et, iBu, iOc, Cy, Ph) at the POSS core. These compounds constitute a library of monosubstituted POSS systems, including thorough spectroscopic and thermal characteristics. These findings could be especially useful for material chemists applying the compounds as modifiers or comonomers for copolymerization reaction, e.g., with olefins.

“…These are one of the most interesting types of deposited metal complexes in which the polymer acts both as carrier and specific ligand around the active metal center. The radiation grafted copolymers of acrylic acid (AA) and other vinyl monomers onto low density polyethene (LDPE) and polytetrafluoroethene (PTFE) is important for the preparation of materials with ion‐exchange properties and metal complexes on their basis 10–15…”

“…Photoinduced grafting has become a very popular technique for the modification and functionalization of polymeric materials because of its significant advantages over other methods, such as the easy and controllable introduction of graft chains without effects on the bulk polymer and the long‐term stability of the grafted chains. The area has been reviewed by a number of authors 1, 2, 15…”

“…The area has been reviewed by a number of authors. 1,2,15 Much work has been done on the improvement of the wettability of PE [mostly low-density polyethylene (LDPE)] through the photografting of hydrophilic monomers onto it. Methacrylic acid (MAA) and acrylic acid (AA) are the most commonly used monomers.…”

Methacrylic acid (MAA) and acrylic acid (AA) were grafted onto high‐density polyethylene (PE) with UV initiation and a range of solvents. With acetone as the solvent, MAA was more easily grafted onto PE when the photoinitiator benzophenone was precoated on PE than when it was dissolved in the monomer solution. The grafting was faster in aliphatic solvents than in polar solvents or a UV‐adsorbing aromatic solvent (toluene). Acetone itself could initiate the photografting of both MAA and AA onto PE when it was mixed with water. The extent of grafting of MAA onto PE showed a maximum when there was about 40% acetone in the mixture. For AA, when the acetone/water concentration was 10%, the extent of grafting increased rapidly with the irradiation time. At higher acetone concentrations, the extent of grafting was low. Atomic force microscopy images showed that the surface topography of PE grafted with MAA in acetone/water was quite different from that obtained when the grafting was performed in other organic solvents. © 2003 Wiley Periodicals, Inc.
