POLYBUTADIENE, MODIFIED POLYBUTADIENE, PREPARATION METHODS FOR BOTH, AND RUBBER-REINFORCED STYRENE RESIN COMPOSITION USING SAME |
摘要 |
<p>Disclosed are a polybutadiene having a controlled microstructure, a narrow molecular weight distribution, minimal gel content, and a low APHA color, a modified polybutadiene, producing methods for both, and a rubber-reinforced styrene resin composition using the same. The polybutadiene of the present invention is characterized in that the ratio (Tcp/ML 1+4 ) of a 5% toluene melting viscosity (Tcp) measured at 25°C and the Mooney viscosity (ML 1+4 ) at 100°C is 2.0 or higher, the molecular weight distribution (Mw/Mn) is 2.80 or less, the gel content is 0.06 wt% or less, and the APHA color is 20 or less.</p> |
