<p>A styrene resin excellent in heat resistance, weatherability, melt stability, and suitability for recycling. It is a styrene copolymer obtained by living polymerization (M w /M n = 1.6-4.0) which comprises isopropenylaromatic units (A) contained in an amount of 5 to 95 wt.% and vinylaromatic units, and has a glass transition temperature (Tg) which satisfies a specific relationship defined by the content of isopropenylaromatic units (A) in the copolymer.</p> |
