Abstract: There is provided a compatibilizer for polyester resin which can produce better compatibility than conventional counterparts, and a polyester resin composition using the compatibilizer. The compatibilizer comprises a polycarbodiimide compound represented by the formula (1) describe below wherein the carbodiimide equivalent of the polycarbodiimide compound is 280 or higher; and in the formula (1), R1 and R2 are residues formed by eliminating a functional group from an organic compound having the one functional group reactive with an isocyanate group; R3 is a divalent residue formed by eliminating two isocyanate groups from a diisocyanate compound; R4 is a divalent residue formed by eliminating two hydroxyl groups from a diol compound; X1 and X2 are bonds formed by reaction of the functional group of the organic compound with one of the two isocyanate groups of the diisocyanate compound; and m and n=1 to 20, m+n≤25, and p=0 to 39, provided that the number of carbodiimide groups in one molecule is 2 to 40.

Abstract: A biodegradable resin composition is usable for producing a molded article having high biodegradability particularly in the ocean. The biodegradable resin composition contains a biodegradable resin and one or more components selected from agarose, sodium alginate, casein, and keratin. The content of the biodegradable resin is 50% by weight or more.
