Abstract:
1. A composition which constitutes a liquid-in-solid polymer emulsion at room temperature, comprising: a thermoplastic polymer matrix (A) selected from the group consisting of polyethylene, polypropylene, polystyrene, polyacrylate, polymethacrylate, poly(1-butene), poly(1-pentene), polymethylpentene and copolymers thereof; 0.1 to about 18 parts by weight of a block copolymer (B) dispersed in 100 parts by weight of the thermoplastic polymer (A) in the form of islands of (B) in the sea of (A); and 0.1 to 20 parts by weight of a liquid compound (C) per 100 parts by weight of the mixture of thermoplastic polymer (A) and block copolymer (B), wherein the islands of the block copolymer (B) encapsulate the liquid compound (C) within the thermoplastic polymer matrix (A), and the islands have a two-layer structure including an outer coat layer made of the block copolymer (B) and a core layer made of the liquid compound (C), and the liquid compound (C) has a low compatibility with the thermoplastic polymer (A) and is phase-separated from the thermoplastic polymer (A).
