A vulcanizable rubber composition comprises an interpenetrating or ionic network (IPN)-promoting resin. The resin comprises side chain functional groups along the resin backbone, which, in the presence of an additive material, form the connections that make up the IPN. In one embodiment, such material is ZnO. A method for forming the rubber composition comprises, in a productive step, mixing the product of the non-productive step, the zinc oxide, and a resin derived from maleic anhydride. The zinc oxide and the resin are simultaneously added to the composition during the productive mixing stage. The rubber composition can be cured and incorporated in a tire component, such as, a tread.

The present disclosure relates to a thermoplastic resin composition and a molded article including the same. More particularly, the present disclosure relates to a thermoplastic resin composition including 100 parts by weight of a styrene-based resin and 1 to 10 parts by weight of a surface modifier and having a skewness (Rsk) of 0.65 to 1.35 and a molded article including the thermoplastic resin composition. In addition, the present disclosure provides a thermoplastic resin composition that is capable of imparting a rough feeling to the surface of a product and has excellent weather resistance while maintaining mechanical properties and processability equal or superior to those of conventional ASA resins; and a molded article including the thermoplastic resin composition. In particular, due to these properties of the thermoplastic resin composition, a product manufactured using the thermoplastic resin composition may have a luxurious appearance without an artificial plastic feel.

A pneumatic tire is formed from a tread rubber composition, which comprises a combination of at least two different solution polymerized styrene-butadiene rubbers (s-SBRs), each extended with oil, and a low Tg traction resin. The low Tg traction resin replaces high Tg traction and the rubber processing oil added during rubber compounding in conventional compounds. The low Tg traction resin is a hydrocarbon resin having a Tg between 100° C. to about 30° C.

An anti-forgery color conversion film includes a photonic crystal structure whose color is converted by an external stimulus such as a breath. The photonic crystal structure includes a first refractive index layer including a first polymer exhibiting a first refractive index; and a second refractive index layer which is alternately laminated with the first refractive index layer and includes a second polymer exhibiting a second refractive index. A consumer who purchases an article including the color conversion film may easily distinguish the authenticity of the article.
