The present invention provides a polymer composition including a first base polymer (A) containing at least a thermoplastic polymer, a second base polymer (B) containing at least a thermoplastic polymer and not having compatibility with the first base polymer (A), and an additive (C) containing at least a substance not having compatibility with any of the first base polymer (A) and the second base polymer (B), the additive (C) being in the form of liquid or slurry at the lower of a pyrolysis temperature of the first base polymer (A) and a pyrolysis temperature of the second base polymer (B). (A), (B) and (C) are phase-separated from each other, and interfaces each located between two of phases of (A), (B) and (C) contacting each other form three-dimensional continuous parallel interfaces.

Polymer composition and molded products formed thereof

The polymer composition comprises a polymer and a liquid compound having poor compatibility with the polymer. When the liquid compound is caused to be held in the polymer in a high concentration, a block copolymer having in the molecule a copolymerized polymer block unit having high compatibility with both of the matrix polymer and the liquid compound is incorporated and dispersed. As a result, the block copolymer serves like a surfactant to form an interface and the liquid compound is enclosed inside the interface to thereby form a liquid-in-solid polymer type emulsion.

Sustained-release thermoplastic polymer composition and product comprising the same

[Object] To provide a polymer composition composed of a functional liquid compound and a polymer, in which the functional liquid compound is phase-separated from but dispersed in the polymer, and a molded product of the polymer composition at lower prices. [Solution] A polymer composition of the present invention includes: a thermoplastic matrix polymer X; a block copolymer Y dispersed in the matrix polymer X; and an additive Z containing an organic compound which is liquid at a melting point of the matrix polymer X or a solution of the organic compound, wherein any two of the matrix polymer X, the block copolymer Y and the organic compound are phase-separated, the block copolymer Y includes a block Y1 which is composed of polymerized monomers having a ring structure and a block Y2 which is composed of monomers different from the monomers of the block Y1, and the organic compound has an intramolecular ring structure or a ring structure formed in a molecule or between molecules due to intermolecular interaction, the organic compound being bleeding-out in the block copolymer Y dispersed in the matrix polymer X.
