ABSTRACT:
A process and apparatus for producing a mixture of polymeric phases wherein a plurality of fluid material having different phases are fed into a phase programmer, and said phase programmer separately and sequentially injects pulses of said polymeric materials into a reservoir. The material may be passed through an extrudate shaping device so as to provide a moasic structure comprising an agglomeration of a plurality of said polymeric phases, each of which phases are substantially non-continuous in any dimension and which are interrupted with substantially no intermixing between phases.
