Abstract
The present invention relates to a new inert matrix having adjustable porosity and hardness. This matrix comprises polycaprolactone having an average molecular weight of between 2000 and 70,000, which is in the form of agglomerated grains having an average diameter of between 50 and 500 .mu.m and has a degree of crystallinity of at least 75%. The invention relates to the method for the preparation of a porous galenic form by means of the said matrix.
