A polystyrene-polyethylene (PS-PE) interpenetrating polymer network (IPN)-like system was prepared by synthesis in situ. The system differs from 'pure' IPN systems in that the PS network is partially grafted onto the PE network. The mean molar mass of the polymer chain between two junction points (/~c) was calculated from the values of uniaxial compression modulus. Differential scanning calorimetry and thermomechanical analysis measurements pointed to a considerable decrease of the crystalline phase in PE with increasing PS content. The melting temperature enhancement of the crystalline phase of PE is discussed.
