Abstract

Disclosed is an extention to (*) teaching the use of a mixture of different precursor materials which can be used to make a morphological composite of the same polymer. Disclosed is a method whereby the same result could be obtained by using materials which would result in similar polymers. This is not obvious, since normal polymer mixtures, copolymers, block copolymers etc use very different materials to get material properties combining the properties of each of the components. A person skilled in the art would not usually consider using polymers with nearly the same structure and, therefore, properties to form a blend.

Morphological Composite Formed from Nearly Identical Polymers

      Disclosed is an extention to (*) teaching the use of a mixture
of different precursor materials which can be used to make a
morphological composite of the same polymer.  Disclosed is a method
whereby the same result could be obtained by using materials which
would result in similar polymers.  This is not obvious, since normal
polymer mixtures, copolymers, block copolymers etc use very different
materials to get material properties combining the properties of each
of the components.  A person skilled in the art would not usually
consider using polymers with nearly the same structure and,
therefore, properties to form a blend.  However, to form
morphological composites, as taught in (*), correctly chosen
precursors for slightly differing polymers will exhibit phase
separation at some stage of the process and react to form two similar
polymers in two phases.
