摘要： Disclosed are a thermal stabilizer-free thermoplastic resin composition and a method of preparing the same. The thermal stabilizer-free thermoplastic resin composition has superior impact resistance, falling ball impact resistance and gloss without using a separate thermal stabilizer. Particularly, the thermal stabilizer-free thermoplastic resin composition improves production efficiency when applied to a squeezing dehydrator because the thermoplastic resin composition is prepared without using a drying process.

摘要： Disclosed is a method for preparing a rubber latex which includes adding a basic solution to an initial reaction hydrophilic monomer and a small amount of fat-soluble monomer when a polymerization conversion ratio is 90% or more to form particles having a small diameter and superior stability, ionizing an end of the particles to secure stability of the particles and growing the formed particles, and thereby obtains a stable latex with a large particle diameter using a minimal amount of emulsifying agent and minimizes gas generation and heat discoloration derived from the emulsifying agent.
