packing coefficient for polymers



 Dear Netters,
 Kitaigorodski in his book Molecular Crystal and Molecules, gives values for
 packing coefficient 0.65-0.77 for the majority of molecular crystals.
 Does someone have an idea of the packing coefficient values for polymers
 (references).
 Thanks in advance
