Procedure

The formulation used for the copolymer is given in Table 2 below. The copolymer was prepared according to the method of Example 1, except that the weight ratio of caprolactone to 1,3-dioxepane was 3 and the reaction temperature was 50° C. The carbodiimide used was Stabaxol P. After removal of the unreacted 1,3-dioxepane, the copolymer was heated to 60° C. and filtered through cheese cloth to remove agglomerated particles resulting from silica gel in the Stabaxol P.
