A method of producing a multiphase polymer is disclosed whereby the phases have the same chemical structure but have different morphological states and thus different properties. This is achieved by forming a mixture of precursors of the polymer, at least one of the precursors having a reaction rate higher than the other precursor or precursors in the mixture. The precursor having the highest reaction rate is then converted to obtain a composite of a polymer and the precursors that are not polymerized. This mixture might also be formed by mixing a soluble polymer with its precursor. The polymer/precursor composite is processed to obtain the structure having different morphological states by either choosing the reaction conditions to convert the unconverted different morphological states by either choosing the reaction conditions to convert the unconverted precursors such that the obtained polymer differs in it morphology/ properties from the first obtained polymer or by applying stress to the composite and then converting the still unreacted precursor or precursors in the composite such that different morphological states are obtained.
A method of preparing a polymer composite comprising an integral structure having a continuous phase and at least one discontinuous phase, said discontinuous phase being constituted by a multiplicity of separated domains, said continuous phase and said discontinuous phase each consisting essentially of polymeric material of the same chemical constitution, said continuous and discontinuous phases exhibiting a different morphological characteristic, said method comprising:
A polymer composite comprising an integral structure having a continuous phase and at least one discontinuous phase, said discontinuous phase being constituted phase and said discontinuous phase each consisting essentially of polymeric material of substantially the same chemical constitution, said continuous and discontinuous phases exhibiting a different crystallinity characteristic.
