An impact-resistant polystyrene resin includes a continuous phase and a plurality of particles dispersed in the continuous phase. The average particle size of the particles is about 0.1 to 4.0 &#x3bc;m, and the average distance between the particles is about 0.3 to 5.0 &#x3bc;m. The impact-resistant polystyrene resin is made from a polystyrene composition including a polystyrene plastic, a styrene block copolymer, a processing aid, and an antioxidant.

A selective laser sintering composition and a selective laser sintering 3D printing method employing the same are provided. The selective laser sintering composition includes a nanoscale inorganic powder and a thermoplastic vulcanizate powder. The temperature difference (&#x394;T) between the onset temperature for melting the thermoplastic vulcanizate powder and the onset temperature at which the thermoplastic crystallizes vulcanizate powder is greater than or equal to 10&#xb0; C. The thermoplastic vulcanizate powder includes a thermoplastic and a crosslinked polymer. The temperature difference (&#x394;T) between the onset temperature for melting the thermoplastic and the onset temperature at which the thermoplastic crystallizes is greater than or equal to 10&#xb0; C. , and the weight ratio of the thermoplastic to the crosslinked polymer is from 1:1 to 1:4.

A flexible transparent material is provided. The flexible transparent material includes a thermoplastic and a plurality of micelles dispersed in the thermoplastic. Each micelle includes a plurality of cross-linked rubber particles and a swelling liquid. The weight ratio of the thermoplastic to the total weight of the cross-linked rubber particles is from 1:5 to 4:5. The weight ratio of the swelling liquid to the total weight of the cross-linked rubber particles is from 1:5 to 2:1.

Flexible transparent material

A thermoplastic vulcanizate is provided, including 10-50 parts by weight of a nylon plastic and 50-90 parts by weight of a cross-linked acrylic rubber polymer. The cross-linked acrylic rubber polymer is dispersed in the Nylon plastic. The cross-linked acrylic rubber polymer is formed by a modified acrylic rubber polymer having a hydrolysable silane group through crosslinking in the presence of water. In the modified acrylic rubber polymer having a hydrolysable silane group, a linkage group represented by formula (I) or formula (II) is between a backbone and the hydrolysable silane group:
