ABSTRACT:
A sizing composition for fine paper that does not encounter machine feed problems in high-speed converting or reprographic operations is not solid at 35.degree. C. and comprises a mixture of 2-oxetanone compounds that are the reaction product of a reaction mixture comprising (a) a feedstock comprising primarily unsaturated fatty acids and (b) a feedstock comprising primarily saturated fatty acids, or acid halides thereof, provided that at least 20 mole % of the reaction mixture fatty acids comprise saturated fatty acids and at least 20 mole % of the reaction mixture fatty acids comprise unsaturated fatty acids.
