Subject: What does the chemical structure of the cross polymerization of Silly Putty

I looked up the structure that you provide for the monomer of Silly Putty, 
but I can't find the chemical structure of the cross polymerization that 
takes place.  I have written a paper on silly putty for my chem class and 
the prof will give me another five points if i can find this information.  
  I have tried the U.S. patent site but they only go back to the year 1976. 
 And because of the location of my school I cannot reach a library that has 
 all of the patents in it.
  If you do not have time to answer my question, do you think you could 
point me in the right direction?
  Thank you very much for your time.
respectfully,
 josh
