Abstract
A self-reinforced polymeric composition of matter comprising a plurality of hard domains dispersed throughout an elastomeric matrix, wherein the plurality of hard domains are formed by thermodynamic phase separation and crosslinking of at least one thermosettable domain block of a polymeric precursor and are substantially bonded to the elastomeric matrix.

A self-reinforced polymeric composition of matter comprising a plurality of thermoset domains dispersed throughout an elastomeric matrix, wherein said plurality of thermoset domains are formed by thermodynamic phase separation and selective crosslinking of at least one thermosettable domain block of a polymeric precursor and are substantially bonded to the elastomeric matrix.
A method for producing a self-reinforced polymeric composition having glassy thermoset domains disposed in an elastomeric matrix comprising the steps of:
- selecting a thermodynamically separable polymeric precursor having at least one thermosettable domain block and at least one matrix block;
- selectively crosslinking the at least one thermosettable domain block of the polymeric precursor with substantially no crosslinking of the at least one matrix block.
