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。介绍了聚乙烯醇生产技术的进展情况,分析了中国外聚乙烯醇的生产消费现状及发展前景,提出了中国聚乙烯醇今后的发展建议。
Polyvinyl alcohol （ PVA） is a water-soluble polymer with wide application. Its preparation methods include direct synthesis from oil-cracked ethylene, natural gas-cracked acetylene method, and calcium carbide-acetylene method. Production technology progress was introduced. Consumption structure and development prospect of polyvinyl alcohol were analyzed. Some viewpoints for the development of China polyvinyl alcohol were also put forward.
