Method of making polymeric compositions and compositions therefor

摘要: A solid composition comprising a homogeneous mixture of thermoplastic resin and from 1 to 80 weight % at least one microbiocide which is insoluble in water, readily dispersible or soluble the temperatures sufficiently high permit plastic manipulation dispersion solution sustained indefinitely upon cooling ambient temperature while diffusivity under such conditions becomes vanishingly small, retains its microbiocidal activity does not degrade react with it dispersed. This compositon provides convenient non-toxic dosage form subsequently mixed second concentration about 0.5 15 obtain containing an effective amount microbiocide.
