The present invention Nos. 1-3 provide a spandex filament which is excellent in view of a recovering ability of elasticity, high tensile strength, and hydrolysis resistance, and a polyurethane which can provide thereof and, further, a polyester polyester diol obtained from a specified diol. Further, the present invention No. 4 provides a polyester polyol containing a polyol having an ultraviolet ray-absorbable group, a lactone-modified polyol therefrom, and a polyester polyol containing other polyol components and adipic acid as constructing component units, and provides a polyurethane having washing resistance obtained therefrom and, further provides a spandex filament comprising the polyurethane. The present invention No. 5 provides a dialkyl amino group-contained additive having a high solubility to a DMAc solvent which protects a spandex polymer from deterioration or discoloration, and which is employed for a spandex polymer having an improved permanent extension property, and a polyurethane composition and a spandex composition having an improved permanent extension property. Still further, the present invention No. 6 provides a polyurethane having a soft feeling, an excellent hydrolysis resistance, a wrinkle resistance, and an adhesive property, and which is particularly excellent as an artificial leather.
A polyester diol containing at least one diol selected from the group consisting of 2-n-butyl-2-ethyl-1,3-propanediol, 2,2-diethyl-1,3-propanediol and 2,4-diethyl-1,5-pentanediol, ∈-caprolactone, and adipic acid as constructing components.
A polyester diol containing a branched aliphatic diol, ∈-caprolactone, and an aliphatic dicarboxylic acid having a carbon number of 10-12 as constructing components.
A polyurethane obtained by allowing to react a polyester diol containing 2,4-diethyl-1,5-pentanediol as a constructing component with an organic diisocyanate.
A polyurethane obtained from a polyether polyol (X) containing a polyol component (A) composed of a polyol (A1) having an ultraviolet ray-absorbable group or a lactone-modified polyol (A2) therefrom and other polyol components (A3), adipic acid (B), and an organic diisocyanate (Y).
A dialkylamino group-contained acrylic-based copolymer formed by an essential copolymer component which includes a dialkylaminoethyl(meth)acrylate represented by a general formula (1) described below and a reactive monomer represented by a general formula (2) described below.
A polyester diol containing at least an aliphatic dicarboxylic acid having a carbon number of 9-12, an aliphatic diol, and ∈-caprolactone as constructing component units.
