摘　　要：由马来酸酐、苯乙烯、丙烯酸羟基酯、丙烯酸、丙烯酸酯等单体经多元共聚制备水溶性聚合物（ＳＭＡＨ），用于改性萘系减水剂，制成ＰＳＬ低坍落度损失缓凝高效减水剂，并进行配制混凝土的系统试验。Monomers such as maleic anhydride, styrene, Hydroxyalkyl acrylate, acrylic acid and acrylate are polymerized to prepare watersoluble polymer(SMAH). Naphthalene sulfonate is modified by SMAH to Prepare PSL low slump loss retarding high range water reducing agent and to make systematic experiments on preparation of concrete.
