Results and discussion

Any other information on results incl. tables

Hydroxyl Radicals Reaction:
OVERALL OH Rate constant = 32.81 E-12 cm³/molecule-sec
Half-life = 0.326 Days (12-hr day; 1.5E6 OH/cm³)
Half-life = 3.912 Hours

Ozone Reaction:
 OVERALL Ozone Rate Constant = 0.175000 E-17 cm³/molecule-sec
 Half-Life = 6.549 Days (at 7E11 mol/cm³)
 Fraction sorbed to airborne particulates (phi): 4.5E-006 (Junge,Mackay)

Applicant's summary and conclusion

Conclusions:
Based on the tertiary (neo) carbon bonding, branched alkyl chain structure and estimated results it is anticipated that vinyl neodecanoate is stronglyresistant to UV degradation.
Executive summary:

Applying the U.S.E.P.A. QSAR model APOWIN version 1.92 the results suggested that Vinyl Neodecanoate is very resistant to UV photodegradation.
