Abstract

Oggetto dell'invenzione è una composizione di materiale suscettibile di essere formata in articoli aventi sostanziale stabilità dimensionale e perfezionate caratteristiche di scioglimento, la quale composizione comprende un mezzo di supporto ed una fase, il mezzo di supporto funzionando come mezzo di dispersione rispetto alla fase, la fase analogamente funzionando come fase dispersa rispetto al mezzo di supporto, la fase essendo presente nella composizione con una concentrazione sufficiente ad effettuare un incremento nello scioglimento degli articoli in confronto con la velocità di scioglimento degli articoli prodotti da una composizione nella quale non è contenuta detta fase, il mezzo di supporto consistendo di un polimero idrofilo solidificato e la fase comprendendo almeno un materiale idrofilo che è sostanzialmente insolubile nel mezzo di supporto comprendente il polimero idrofilo.The object of the invention is a composition of material capable of being formed in articles having substantial dimensional stability and improved melting characteristics, which composition comprises a support means and a phase, the support means operating as a dispersion means with respect to the phase, the phase similarly functioning as a dispersed phase with respect to the support medium, the phase being present in the composition with a concentration sufficient to effect an increase in the dissolution of the articles in comparison with the dissolution rate of the articles produced by a composition in which said composition is not contained phase, the support means consisting of a solidified hydrophilic polymer and the phase comprising at least one hydrophilic material which is substantially insoluble in the support medium comprising the hydrophilic polymer.
