JEFFAMINE? polyetheramine product series JEFFAMINE? 聚醚胺产品系列 Amine Curing reaction Applications 胺固化剂反应及应用 4. Questions and Summary 问题和小结 JEFFAMINE? PolyetheraminesJEFFAMINE? 聚醚胺 Monoamines, diamines, and triamines 一元胺，二元胺，和三元胺 Flexible polyether backbone 弹性聚醚主链 Polypropylene glycol, polyethylene glycol-based 聚丙二醇，聚乙二醇为基本链段 Wide molecular weight range – 150 to 5000 宽广的分子量范围 – 150 至 5000 Structure Overview结构概况 Polyetheramine Structural Elements聚醚胺结构原理 Amine end groups 端胺基基团 In PPG-based amines, primary amine next to methyl group 在以聚丙二醇为基团的胺类来看，伯胺接在甲基基团上 Hindrance means slower reaction 空间位阻使反应较慢 Slower is better in some applications 在某些应用中反应速度越慢越好 Most PEG-based diamines capped with PO, giving same type of amine group as PPG-based amines 多数以聚乙二醇为基团的二元胺用环氧丙烷封端，与聚丙二醇基团的胺类表现出同样类型的胺基团 Polyetheramine Structural Elements聚醚胺结构原理 Polyether backbones 聚醚胺主链 Polypropylene glycol – most common; relatively hydrophobic; good mechanical properties 聚丙二醇 – 最常见；相对憎水性；良好的机械性能 Polyethylene glycol – not so common in curing agents; hydrophilic; important in some other applications 聚乙二醇 – 在固化剂中不是很常见；亲水性；主要应用在其它一些应用领域 Structure/Property Relationships结构－特性关系 Performance Comparison 性能比较 Performance Comparison (cont.) 性能比较 (续) Performance Comparison (cont.) 性能比较 (续) With cycloaliphatic amines 与脂环胺比较 Cycloaliphatics good for higher temperature, chemical resistance 脂环胺优点在于耐高温和耐化学性 Tend to be more brittle 趋势是脆性更大 Blends give higher Tg than JEFFAMINE? amines alone, better flexibility than the cycloaliphatic amine alone 混合使用可以提供比单独使用 JEFFAMINE? 胺更高的 Tg ，比单独使用脂环胺更好的弹性。 With polyamides 与聚酰胺比较 Polyamides generally higher in viscosity and color , good overall properties 聚酰胺通常粘度和颜色都比较高，全面的性能比较好。 JEFFAMINE ? amines can serve as reactive diluents, giving goo
