Title:
HEAT-DECOMPOSABLE POLYMER
Document Type and Number:
WIPO Patent Application WO/2003/095523
Kind Code:
A1
Abstract:
A heat-decomposable polymer characterized by being produced by polymerizing a monomer having a dibenzofulvene structure in an oxygen atmosphere. The polymer easily causes a decrease in the molecular weight by heating, thus being not only usable as a high-molecular radical polymerization initiator but also easy of disposal.
