【摘要】 利用二甲胺和异丙胺在适宜的条件下对酚醛树脂进行改性,得到了胺改性酚醛树脂。将其与聚氧化乙烯(PEO)组成新型的双元助留体系,应用于热磨机械浆(TMP)抄纸工艺中,取得了很好的助留效果更多还原

【Abstract】 The syntheses of phenol-formaldehyde resin modified with dimethylamine or isopropylamine under suitable conditions were conducted. The obtained amine-modified phenol-formaldehyde resins comprise novel retention systems with polyethylene oxide, which can be used to improve TMP pulp retentions.更多还原
