Golf Balls Dissolve on the Moon?

I’m having a hard time finding much info on this, but this article:

http://www.cnn.com/2009/SPORT/11/04/littering.golf.balls/

has a throw-away line about the golf balls left on the moon in the early 1970’s would be long gone because they would “dissolve in the extreme temperatures.”

Really? That just doesn’t sound right to me. Would golf balls dissolve on the moon? At all? Within 40 years?

Not so much dissolve as crumble. The volatile compounds in the plastics outgas from the vacuum and extreme temperature cycles, and the unfiltered UV from the sunlight would break down what’s left. At best, you’d have an intact-looking golf ball that would disintegrate into dust at the slightest touch.
