FIELD: chemistry.
SUBSTANCE: invention relates to a polymer composition which forms a "liquid in solid substance" polymer system at room temperature and having the prolonged release effect of a liquid organic compound, and articles made from said composition. The composition contains 0.1-50 pts. wt thermoplastic polymer (A) and 0.1-20 pts. wt block-copolymer (B). Block-copolymer (B) contains a block (b1) having high compatibility with a thermoplastic polymer (A), but low compatibility with a liquid compound (C), and a block (b2) having high compatibility with the liquid compound (C), but low compatibility with thermoplastic polymer (A). Block-copolymer (B) acts like a surfactant by forming a boundary surface between polymer (A) of the matrix and liquid compound (C).
EFFECT: composition enables to hold a liquid compound dispersed therein with high concentration.
