摘要:
A high molecular material and a medical material which is a mixed material containing a copolymer A produced by copolymerization of a monomer composition containing a monomer having a side chain represented by the formula (1) ##STR1## (R.sup.1, R.sup.2, R.sup.3 ; H or a C1-4 alkyl group) and a hydrophobic monomer, and one or more sorts of hydrophobic polymer B other than the copolymer A; wherein structure of said mixed material shows phase separation in which domains of several hundred micrometers or less in size consisting of the copolymer A are uniformly distributed in a phase consisting of said hydrophobic polymer B. A liquid high molecular composition in which the copolymer A and the hydrophobic polymer B are dissolved in a mixed solvent consisting of a halogenated hydrocarbon solvent and a lower alcohol solvent, which has turbidity of 60% or less.
摘要:
Stable peroxyesters containing both conjugated diene and peroxidic groups in their molecule; e.g., t-butylperoxysorbate, t-hexylperoxysorbate, 1,1,3,3-tetra-methylbutylperoxysorbate, are copolymerizable with other polymerizable monomers and the said compounds are useful for polymerizing monomers as free radical initiators.
摘要:
[Problem]A method by which a flame proofing property can easily be provided to polyester fiber having long-term stable color and excellent mechanical properties, particularly, a resin composition and a flame proofing method needed for flame retardant spun-dyed polyester fiber which is excellent in light resistance and durability, and is capable of coloring any of various colors, and also, is environment-friendly, are strongly desired.□Solution□There is provided a flame retardant spun-dyed polyester fiber obtained by melt-spinning a flame retardant polyester resin composition comprising a flame retardant comprising at least one inorganic phosphorus-nitrogen based compound selected from the group consisting of ammonium polyphosphate, melamine polyphosphate and phosphazenes; colorant; and thermoplastic polyester resin, characterized in that content of said inorganic phosphorus-nitrogen based compound is 0.1 to 12% by mass, content of said colorant is 0.01 to 5% by mass, and content of said thermoplastic polyester resin is 83 to 99.89% by mass, based on the total weight of said polyester resin composition. Particularly, when disposed polyester is used as the thermoplastic polyester resin, it contributes to material recycle as well.
