Abstract:
A perfume-containing controlled release biodegradable resin composition, which comprises a biodegradable resin comprised of a random or block copolymer polyester represented by the following formula (1): ##STR6## wherein R.sup.1 represents a hydrocarbon group having 1 to 15 carbon atoms, which is a divalent organic group that may have a double bond or an oxygen atom but does not have a group represented by a formula ##STR7## where the symbol ""*"" represents an asymmetric carbon atom, and each of m and n is 0 or an integer of from 100 to 9,000, with the proviso that m+n is within the range of from 200 to 10,000,wherein molar ratio of the structural units [I] and [II] is from 1-99:99-1 when m and n are not 0 and a number-average molecular weight of the polyester is from 5,000 to 1,000,000, and a perfume held in said biodegradable resin.
