Low-Melting Elemental Metal or Fusible Alloy Encapsulated Polymerization Initiator for Delayed Initiation

摘要

An encapsulated composition for polymerization includes an initiator composition for initiating a polymerization reaction, and a capsule prepared from an elemental metal or fusible alloy having a melting temperature from about 20° C. to about 200° C. A fluid for polymerization includes the encapsulated composition and a monomer. When the capsule melts or breaks open, the initiator is released.
