Described is the use of homopolymers of (epsilon caprolactone) defined according to the structure: ##STR## and, optionally, ##STR## as controlled release materials for physiological or psychological diagnostic compositions, pheremones, insect repellent compositions, animal repellent compositions, and/or aroma augmenting or enhancing media for use in perfume compositions or perfumed articles or colognes; wherein n represents an integer of from about 500 up to about 1,200 with the proviso that the average "n" varies from about 600 up to about 800. Also described are mixtures of such homopolymers with other polymers such as polyethylene, polypropylene, mixtures of polyethylene and polyvinyl acetate, copolymers of ethylene and vinyl acetate, and the like, useful for controlled release of such physiological or psychological diagnostic compositions, pheremones, insect repellents, animal repellents and perfume materials into a gaseous environment surrounding the polymer matrix. Also described are methods for blending such polycaprolactone homopolymers whereby a first amount of a liquified polycaprolactone is admixed in an extruder, for example, with a diagnostic material and/or scent imparting material and/or an animal repellent material and/or insect repellent material and/or a pheremone material. The solidified pellets may if desired, then be mixed in, for example, a second extruder with a second amount of unscented polycaprolactone or other polymer, e.g., polyolefin, the second amount of polymer being the same or somewhat larger then the first amount. The mixture thus obtained may again be solidified and, if desired, repelletized. The resulting pellets may, if desired, be formed into functional articles by means of, for example, injection molding.

1. A hollow, totally enclosed structure comprising a thin shell totally enclosing an inner void, said thin shell having a lower base and an upper base and a side wall portion, said side wall portion connecting said upper base and said lower base in a substantially continuous fashion, said side wall being substantially impermeable to gas, said upper base being permeable to gas passing therethrough and said lower base being permeable to gas passing therethrough, and contained within at least a major portion of said void, polymeric particles which consist essentially of polymer and a functional fluid, said functional fluid being selected from the group consisting or aromatizers, deodorizers, animal repellents, pheremones, insect repellents, insect attractants, materials capable of diagnosis of physiological and/or psychological aberrations or malfunctions of mammalian species and medicinal products, said functional fluid being capable of being volatilized in the presence of an air stream passing from said lower base to said upper base through said permeable upper base and lower base in a direction substantially parallel to said outer wall, said polymeric particles being produced by means of: (a) forming a first flowable mass of poly(epsilon caprolactone) homopolymer having the structure: ##STR## and from 0 up to minor proportion of the structure: ##STR## wherein n is an integer of from about 500 up to about 1,200 with a proviso that the average n in the system varies from about 600 up to about 800 with from about 1% up to about 30% by weight of said functional fluid; (b) causing the flowable mass to be formed into an extruded rod using an extruder; and (c) pelletizing the thus formed extruded rod to form pellets in the solid state; said poly(epsilon caprolactone) homopolymer containing a stabilizer. 2. The article of manufacture of claim 1 wherein the functional fluid is a perfumed substance and the perfumed substance is compatible with said poly(epsilon caprolactone) homopolymer. 3. The article of manufacture of claim 1 wherein the functional fluid is an animal repellent, the animal repellent is an aliphatic ketone, and the aliphatic ketone is compatible with said poly(epsilon caprolactone) homopolymer. 4. The article of manufacture of claim 1 wherein the functional fluid is a substance capable of diagnosis of physiological and/or psychological aberrations or malfunctions of mammalian species. 5. The article of manufacture of claim 3 wherein the ketone is an aliphatic or alicyclic ketone containing from about 6 up to about 20 carbon atoms. 6. The article of manufacture of claim 1 wherein the poly(epsilon caprolactone) is further admixed with polyethylene.
