BISPHENOL MONOESTER-BASED STABILIZER COMPOSITION, THERMOPLASTIC POLYMER COMPOSITION AND METHOD OF MANUFACTURING THE SAME, THERMOPLASTIC POLYMER MOLDED PRODUCT, AND METHOD OF STABILIZING THERMOPLASTIC POLYMER

摘要

A bisphenol monoester-based stabilizer composition is provided to improve heat-proof colorability of a thermoplastic polymer compared with a conventional stabilizer composition. A bisphenol monoester-based stabilizer composition is obtained by condensing a dialkylphenol composition with acetaldehyde 1 mole based on the phenolic hydroxide group 2.00 mole contained in the dialkylphenol composition, and reacting the reactant and an acrylic acid based compound 1 mole of the chemical formula(2). The dialkylphenol composition contains 2,4- di -tert- pentyl phenol as a main component and is represented by the following chemical formula(1). In the chemical formula(2), X shows halogen, hydroxyl group, C1-3 alkoxy group or a group showing H2C=CH-C(O)-O-.
