Title:
POLYMER ULTRAVIOLET LIGHT ABSORBER FOR FIBER AND FLAME- RETARDANT ACRYLIC FIBER CONTAINING THE SAME
Document Type and Number:
Japanese Patent JP2002363226
Kind Code:
A
Abstract:
To obtain both a polymer ultraviolet light absorber having improved transparency and stability with time and light resistance and a flame-retardant acrylic fiber.
The polymer ultraviolet light absorber for fiber comprises a copolymer which is obtained by polymerizing a benzophenone-based ultraviolet absorption monomer, a benzotriazole-based ultraviolet absorption monomer and a copolymerizable vinyl monomer as essential components and has a mass- average molecular weight (Mw) value of 1,000-10,000.
