Procedure

199.3 g of a mixture containing di-n-butyl diacetoxy tin, tri-n-butyl acetoxy tin and 1,1,3,3-tetra-n-butyl-1,3-diacetoxy distannoxane was obtained by carrying out the same method as step (2-2) of Example 2 with the exception of using 200.1 g of the mixture obtained in step (5-1) instead of the mixture obtained in step (2-1). The content of di-n-butyl diacetoxy tin in this mixture was 63.7 wt %, the content of tri-n-butyl acetoxy tin was about 1 wt %, and the content of 1,1,3,3-tetra-n-butyl-1,3-diacetoxy distannoxane was 32.3 wt %.
