摘要
聚乙烯醇(PVA)是一种用途广泛的水溶性高分子聚合物,其制备方法有乙烯直接合成法、天然气裂解乙炔和电石乙炔法。分析了聚乙烯醇的生产技术与生产现状、消费结构和进出口状况,对我国聚乙烯醇的发展提出了几点建议。
Polyvinyl alcohol （PVA） is a water-soluble polymer with wide applications. Its preparation methods include direct synthesis from oil-cracked ethylene, natural gas-cracked acetylene and synthesismethod from calcium carbide-acetylene. Production technology and current situation of production, consumption structure and import and export for polyvinyl alcohol were analyzed in this paper. Some views of the development of China polyvinyl alcohol have been mentioned.
