This invention relates to a thermoplastic resin composition comprising a thermoplastic resin (A) and a reactive functional group-containing thermoplastic resin (B), which has a specific structure in the morphology of the resin composition observed by transmission electron tomography, and the relaxation time T1C of each carbon nucleus by the solid NMR measurement of the thermoplastic resin composition containing a polyamide resin is kept in a specific range. The composition is excellent in the balance between contradictory properties such as impact resistance and heat resistance, remarkably exhibits a peculiar viscoelastic behavior not observed in the conventional polymeric materials, and is remarkably excellent in impact energy absorbing performance and vibration energy absorbing performance at the time of high-speed deformation.

The present invention provides a hot-melt adhesive that has a sufficiently long usable life and that exhibits superior strength and heat resistance. The present invention relates to a hot-melt adhesive composition that contains a hydrocarbon-based cyclic polymer, an alpha-olefin-based polymer, and a tackifying resin.

An embodiment of the present invention relates to a heat-resistant coating composition, a heat-resistant coating film, a heat-resistant coating film-attached substrate, or a method for preparing same, said heat-resistant coating composition including a siloxane-based binder (A), an aluminum powder (B), and an anti-corrosive pigment containing a magnesium phosphate-based compound.

The present invention provides a resin composition comprising polylactic acid and aliphatic polyester carbonate, which has practically adequate heat-resistance temperature, moldability, thermostability, solvent resistance and high mechanical strength, as well as a molded article thereof. In the resin composition, the Vicat softening point is 60 DEG C. or more, the tensile modulus of elasticity is 0.9 GPa or more, the modulus in flexure is 0.6 GPa or more, and the mixing ratio of polylactic acid (A) and aliphatic polyester carbonate (B), in terms of the ratio of (A)/(B) by weight, is 95/5 to 5/95. Further, the present invention provides a biodegradable injection-molded article having improvements in mechanical characteristics and impact resistance and superior disposal properties, particularly having strength enough to make it usable as a headgear material for use in helmets. The biodegradable injection-molded article is excellent in impact resistance, comprising mainly polylactic acid (A) and aliphatic polyester (E) and/or aliphatic polyester carbonate (B). This injection-molded article has a flexural strength of 30 MPa or more and an Izod impact strength of 3 kJ/m2 or more, and it is used as helmet headgear.
