    • A perfume-containing controlled release biodegradable resin composition which can release aroma of the included perfume gradually without changing its perfume tone and can be used in such applications as deodorants, etc. The resin composition includes a biodegradable resin which is a random or block copolymer polyester represented by the following formula (1): ##STR1## wherein R.sup.1 is a hydrocarbon radical having 1 to 15 carbon atoms, which is a divalent organic group that may be have a double bond or an oxygen atom but does not have a group represented by the formula ##STR2## wherein the symbol "*" is an asymmetric carbon atom. Each of m and n is 0 or an integer of 100 to 9,000, provided that m+n is within the range of 200 to 10,000. The molar ratio of the structural units [I] and [II] is 1-99:99-1 when m and n are not 0 and the number average molecular weight is 5,000 to 1,000,000, and a perfume such as a cyclic ether, a natural plant perfume, etc., is held in the biodegradable resin.
    • 一种含香料的控释生物降解性树脂组合物,其可以逐渐释放所含香料的香味,而不改变其香料色调,并且可用于除臭剂等的应用中。树脂组合物包括可生物降解的树脂,其是无规或嵌段共聚物聚酯 由下式(1)表示:其中R 1是具有1至15个碳原子的烃基,其是可以具有双键或氧原子但不具有由下式表示的基团的二价有机基团:其中 符号“*”是不对称碳原子。 m和n分别为0或100〜9000的整数,条件是m + n在200〜10000的范围内。 当m和n不为0且数均分子量为5,000至1,000,000时,结构单元[I]和[II]的摩尔比为1-99:99-1,环状醚, 天然植物香料等保存在可生物降解的树脂中。
