  • Homo-, co- or multicomponent thermoplastic polymer dispersed in a thermoset resin
    Patent number: 5834537
    Abstract: The present invention relates to a curable thermosetting resin composition having enhanced fracture toughness as a results of the incorporation of reactive thermoplastic oligomers therein. More specifically, the present invention relates to a composition comprising a thermoset resin which contains fluorine and containing at least one fluorine containing thermoplastic homopolymer component which is soluble in the thermoset. Said thermoplastic polymer undergoes an in-situ phase separation process during cure to form a microphase separated multiphase thermoset material.
    Type: Grant

  • Homo-, co- or multicomponent thermoplastic polymer dispersed in a thermoset resin
    Patent number: 5827907
    Abstract: A composition having enhanced fracture resistance comprising a heat curable reaction product of a fluorine-containing thermoset material and a fluorine-containing homopolymer, wherein the cured reaction product comprises the thermoset material having a plurality of discrete phases of said fluorine-containing homopolymer dispersed therein, the homopolymer phases being in the range of micron to submicron size.

  • Process for making a foamed elastomeric polymer
    Patent number: 5804607
    Abstract: The present invention relates to a process for forming a foamed elastomeric polymer. The process involves forming a reverse emulsion of liquid droplets in a continuous liquid phase of polymer precursor and then polymerizing the precursor to entrap uniformly distributed droplets of the liquid in pores formed in the polymer bulk. The liquid in the pores is then removed under supercritical conditions.
    Type: Grant

  • Process for making a foamed polymer
    Patent number: 5700844
    Abstract: The invention relates to a process for making a foamed polymer. The process involves (a) dispersing thermally degradable solid particles in polymer precursor; (b) crosslinking the polymer precursor to form a rigid, crosslinked polymer without degrading the particles; and (c) heating the polymer to degrade the particles and form the polymer foam.
