POLYMERKOMPOSITION INNEHAOLLANDE SKUMREGLERINGSMEDEL MED KORT VARAKTIGHET

摘要

The invention relates to a foamable composition comprising an aromatic alkenyl polymer, a foaming agent, and a foam regulator that works for a limited period of time and which can reduce the melt viscosity of the polymer in the molten phase but which cannot be mixed with the polymer in the solid phase and causes no damage to it.
