Title: Low-melting elemental metal or fusible alloy encapsulated polymerization initiator for delayed initiation

Patent ·
OSTI ID:1233362

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.degree. C. to about 200.degree. C. A fluid for polymerization includes the encapsulated composition and a monomer. When the capsule melts or breaks open, the initiator is released.
