ABSTRACT OF THE DISCLOSURE The invention relates to compositions useful as insulat- ors for electrical conductors and soldering wire and a process for preparing the compositions. An interpenetrating network is obtained by blending a partially hydrogenated block copolymer with an engineering thermoplastic resin having an apparent crystalline melting point of between 120°C and 300°C and a vis- cosity at a temperature Tp of between 150°C and 400°C and a shear rate of 100 sec.-1 of between ? minus 2,000 poise and ? plus 3,000 poise, the viscosity ? being the viscosity of the partially hydrogenated block copolymer at a temperature Tp and a shear rate of 100 sec.-1.
