  • Patent number: 5272204
    Abstract: Polymer/polyol compositions, obtained by polymerizing an ethylenically unsaturated monomer in situ in a polyol in the presence of inner-olefin containing at least 5 carbon atoms, are of lower viscosity and can provide polyurethanes having improved properties. Polymer/polyol compositions, obtained by polymerizing an ethylenically unsaturated monomer, in situ in a polyol in the presence of an azo compound and a peroxide having a 10 hours half-life period temperature which is lower by at least 10.degree. C. than that of the azo compound, have improved stability even at higher styrene content.

  • Patent number: 5268452
    Abstract: Unsaturated polyester resins of the type already having reactive liquid polymers reacted into the backbone of the resins, are cured in the presence of a reactive liquid polymer additive admixed with the prereacted unsaturated polyester resin. Heating of this system during cure causes the reactive liquid polymer additive to miscibilize with the unsaturated polyester resin. The unsaturated polyester resin modified in the manner described above shows a significant enhancement in toughness as measured by fracture energy over unmodified counterparts or counterparts modified by known methods of adduction or admixing alone.
