摘要： The present invention relates to a thermoplastic resin composition and an exterior material including the same. The present invention has an effect of providing a thermoplastic resin composition that has low gloss while having mechanical properties and processability equal or superior to those of conventional ASA resins, has excellent processability and adhesion in manufacture of a co-extruded product due to improvement in viscoelastic properties, and is capable of reducing defects in surface appearance; and an exterior material including the thermoplastic resin composition.

摘要： A method of measuring fracture strength of a superabsorbent polymer in order to predict a generation amount of fine powder is provided. Effects of many different treatments for increasing strength of the superabsorbent polymer may be evaluated by measuring a force at a time point when single particles having a uniform particle size of the superabsorbent polymer are fractured by pressurizing the particles at a constant rate within a predetermined range.
