Mixtures of low density polyethylene with various types of silica were investigated. The polymer matrix was crosslinked by initiation with peroxides. Four grades of silica were characterized by different methods. The presence of SiO 2 was found to lead to the formation of bound polymer, its proporti
The viscosity behavior of aqueous suspensions of silica particles with physically adsorbed polyethylene oxide (PEO) molecules was investigated in relation to the adsorbed layer density and concentration of nonadsorbed polymer in the suspending fluid. Adsorption studies revealed the presence of two p
The maleinisation of LDPE in various aromatic solvents in the presence of radical initiators was studied. A strong influence of the solvent on the reaction was observed and attributed mainly to the presence of benzylic hydrogens in the solvent molecule. It was confirmed that, during the polymer male
