Abstract
The present invention is directed to a free radical control agent of the structural formula:
Description
Claims
  • 1. A free radical control agent of the structural formula:
  • 2. A free radical control agent according to claim 1 wherein Y represents a functional group selected from the group consisting of —C(R′)2CN, —C(CH3)2Ar, —C(CH3)2COOR′, —C(CH3)2CONHR′, —C(CH3)2CH2C(CH3), —CH(CH3)Ar, —CH2Ar, —C(CH3)3, —CR′2COOH, —C(R′)(CN)—(CH2)n—COOH, and —C(R′)(CN)—(CH2)n—OH; wherein R1 represents a linear or branched hydrocarbon containing from 1 to 12 carbon atoms; wherein Ar represents an unsubstituted or substituted phenyl, napthyl, anthracenyl, pyrenyl or pyridyl group; and wherein n represents an integer from 1 to 8.
  • 3. A free radical control agent according to claim 1 wherein R1 is (CH2)m where m ranges from 1 to 4.
  • 4. A free radical control agent according to claim 1 wherein Y represents a function group selected from the group consisting of benzyl, picolyl, and t-butyl.
  • 5. A free radical control agent according to claim 1, wherein R1 is (CH2)9, R2 and R3 are hydrogen, R4 is —COOH, Y is benzyl, and the free radical control agent is S-benzyl-S′-(11-undecanoic acid) trithiocarbonate.
  • 6. A free radical control agent according to claim 1, wherein R1 is CH2, R2is (CH2)8, R3 is hydrogen, R4 is —OH, Y is benzyl, and the free radical control agent is S-benzyl-S′-(2-hydroxydecyl) trithiocarbonate.
  • 7. A free radical control agent according to claim 1, wherein R1 is CH2, R2 is (CH2)8, R3 is hydrogen, R4 is —OH, Y is 4-picolyl, and the free radical control agent is S-(4-Picolyl)-S′-(2-hydroxydecyl) trithiocarbonate.
  • 8. A polymer derived from the free radical control agent of claim 1 and at least one monomer selected from the group consisting of styrene, substituted styrene, alkyl acrylate, substituted alkyl acrylate, alkyl methacrylate, substituted alkyl methacrylate, acrylonitrile, methacrylonitrile, acrylamide, methacrylamide, N-alkylacrylamide, N-alkylmethacrylamide, N,N-dialkylacrylamide, N,N-dialkylmethacrylamide, isoprene, 1,3-butadiene, ethylene, vinyl acetate, vinyl chloride, and vinylidene chloride.
  • 9. A polymer derived from the free radical control agent of claim 1 and at least one monomer selected from the group consisting of styrene, 1,3-butadiene, and isoprene.
  • 10. A tire comprising the polymer of claim 8.
