The 6-deoxy-6-aminocelluloses—or “aminocelluloses”—are a class of synthetic natural cellulose derivatives which are mostly aqueous soluble and have excellent film-forming properties. Recent studies have connected these properties at the molecular level with protein-like self-associative behaviour for a range of aminocelluloses including a 6-deoxy-6-(ω-aminoethyl) aminocellulose AEA-1 with the association being a two-stage process—a reversible oligomerisation followed by further (semi-reversible) aggregation into larger structures. Here, we synthesise and compare a new 6-deoxy-6-(ω-aminoethyl) aminocellulose AEA-1′ with different degree of substitution with one with further alkyl derivatisation, namely 6-deoxy-6-(ω-hydroxyethyl) aminocellulose HEA-1′. As with AEA-1, sedimentation velocity and sedimentation equilibrium in the analytical ultracentrifuge still show a two-stage process for both AEA-1′ and HEA-1′, with the latter giving higher molar masses. The consequences of these properties for use as consolidants for archaeological wood are considered.

6-脱氧-6-氨基纤维素（或“氨基纤维素”）是一类合成的天然纤维素衍生物，主要是水溶性的，并具有出色的成膜性。最近的研究已在分子水平上将这些特性与一系列氨基纤维素（包括6-脱氧-6-（ω-氨基乙基）氨基纤维素AEA-1）的类蛋白质自缔合行为联系在一起，缔合是一个两阶段过程，可逆的低聚，然后进一步（半可逆）聚集成更大的结构。在这里，我们合成并比较了一种具有不同取代度的新型6-脱氧-6-（ω-氨基乙基）氨基纤维素AEA-1'，其中一种具有进一步的烷基衍生化作用，即6-脱氧-6-（ω-羟乙基）氨基纤维素HEA -1'。与AEA-1一样，分析型超速离心机中的沉降速度和沉降平衡仍然显示出AEA-1'和HEA-1'的两阶段过程，后者的摩尔质量较高。考虑了这些性质用作考古木材的固结剂的后果。
