  • Patent number: 8513343
    Abstract: The present invention relates to unsaturated polyester resin composition comprising an unsaturated polyester resin, a manganese compound, a 1,3-dioxo compound and a base; the molar ratio between the dioxo compound and the basic functionality of the base is from 170:1 to 1:30 and the resin composition being curable with a peroxide. The present invention further relates to a process for radically curing such a resin composition wherein a peroxide is added to the resin composition and the curing is effected in the absence of cobalt.

  • Patent number: 8013088
    Abstract: A polymerization reaction mixture for the cationic polymerization of unsaturated biological oils (e.g. vegetable oils and animals oils) based on the cationic reaction of double bonds initiated by superacids is provided. The polymerized oils have a viscosity about 10 to 200 times higher than the initial oil and relatively high unsaturation (only about 10-30% lower than that of initial oils).

  • Patent number: 7501479
    Abstract: A method for the cationic polymerization of unsaturated biological oils (e.g., vegetable oils and animal oils) based on the cationic reaction of double bonds initiated by superacids is provided. The process occurs under very mild reaction conditions (about 70-110° C. and atmospheric pressure) and with short reaction times. The polymerized oils have a viscosity about 10 to 200 times higher than the initial oil and relatively high unsaturation (only about 10-30% lower than that of initial oils).

  • Patent number: 5770653
    Abstract: A resin composition includes a dicyclopentenyl-group containing unsaturated polyester resin, a phenothiazine derivative (a) and an anion producing compound (b). On the other hand, resin composition includes a thermosetting resin, a phenothiazine derivative (a), an anion producing compound (b) and a phosphorous ester (c). A manufacturing method of resin composition includes the step of obtaining a dicyclopentenyl-group-containing unsaturated polyester by polycondensing unsaturated polyester material including a compound having a dicyclopentenyl group, and the step of mixing a cross-linking monomer with the obtained dicyclopentenyl-group-containing unsaturated polyester, wherein the phenothiazine (a) and the anion producing compound (b) are added in at least one of those steps.

  • Patent number: 4267279
    Abstract: Gel-time drift may be reduced in promoted polyester resin systems by incorporation of an amine salt in accordance with the disclosed compositions and methods. The amine salt is a salt-like reaction product of an amine and a carboxylic acid-containing moiety. For free-amine type promoted resin systems, an amine salt may be substituted for the amine promotor to provide a low-energy curable polyester resin system having the advantages of a promoted system as well as being stabilized against gel-time drift. Comparative data show suppression of gel-time drift of resin samples containing an amine salt to as low as 7 percent of gel-time drift of counterpart free-amine promoted resin system samples.
