Cold ionizing radiation sterilization

A hydratable gel-forming polymer may be sterilized by chilling the polymer below ambient temperature and sterilizing the chilled polymer using ionizing radiation (e.g., E-Beam radiation). Doing so may reduce the degradation in physical properties caused by ionizing radiation sterilization of the polymer while at ambient temperature, and may preserve or retain desired hydration or gel-forming characteristics. The polymer might be a chitosan and/or further polysaccharides.

本发明涉及一种通过LCST化合物来降低或防止聚异丁烯颗粒在水性介质中附聚的方法以及由此获得的高纯异丁烯。本发明还涉及包含所述高纯异丁烯或由其得到的聚异丁烯产品。

Dendrobium polysaccharide nanocellulose hydrogel

本发明公开了一种石斛多糖纳米纤维素水凝胶，通过以改性纳米纤维素、石斛多糖和聚乙烯醇作为主要原料；其中石斛多糖是取自于铁皮石斛，改性纳米纤维素是纤维素经过改性剂处理后制得，改性剂为3‑[2‑(五氟己基)乙氧基]‑1,2‑环乙氧基丙烷、5‑氯‑1‑(4‑哌啶基)‑2‑苯并咪唑吲咪和二甲基二烯丙基氯化铵的混合物；改性纳米纤维素与石斛多糖，聚乙烯醇之间都具有较好的相容性；本发明制得的水凝胶为具有高分子网络结构的聚合物，含有亲水基团和网状结构，能够将石斛多糖包裹住，具有较强的稳定性。以石斛多糖纳米纤维素水凝胶为主要原料的精华露生物相容性好，同时能够延缓肌肤衰老，并且其热稳定性能好，在较高温度下放置一段时间后，依然具有较好的抗衰老等作用。
