• An enclosure member substantially impermeable to the transmission of solvents and fuels
  申请人：KONINKLIJKE EMBALLAGE INDUSTRIE VAN LEER B.V.

  公开号：EP0035292A2

  公开（公告）日：1981-09-09

  The present application relates to enclosure members consisting essentially of solid, non-aromatic polymers that have a linear carbon to carbon backbone structure and having a plurality of free hydrogen atoms attached to the carbon atoms with a permeability to wet solvents and fuels of less than 1/50, optionally less than 1/200 of the permeability of untreated enclosure members having a thickness of 1 mm. Said low permeability is due to the presence of a coating on at least the inner surface of said enclosure members, having a portion of the hydrogen atoms replaced by sulphonic acid or sulphonate groups, consisting of a cured thin layer (of at least 2 µm) of condensation products of formaldehyde and melamine of formaldehyde and urea. Evidently the application relates also to a method of preparing said enclosure members.

  本申请涉及主要由固态非芳香族聚合物组成的围护结构，这些聚合物具有线性碳-碳骨架结构，碳原子上连接有多个游离氢原子，其对湿溶剂和燃料的渗透性小于 1/50，或小于厚度为 1 毫米的未处理围护结构渗透性的 1/200。所述低渗透性是由于至少在所述围护结构的内表面存在一层涂层，其部分氢原子被磺酸或磺酸盐基团取代，该涂层由甲醛和三聚氰胺与甲醛和尿素的缩合产物的固化薄层（至少 2 微米）组成。显然，该申请还涉及一种制备上述围护结构的方法。

  公开（公告）日：2002-04-11

  An antiseptic composition useful in destroying the infectivity of infectious proteins such as prions is disclosed. The antiseptic composition is preferably maintained at a pH of 4.0 or less which allows for an environment under which the active component destroys infectivity. The composition may be added to blood, blood products, collagen, tissues and organs prior to transplantation. The composition also may be added to livestock feed to denature any prions in the livestock. Methods of denaturing infectious proteins are also disclosed.

  An antiseptic composition useful in destroying the infectivity of infectious proteins such as prions is disclosed. The antiseptic composition is preferably maintained at either a low pH of 4.0 or less or a high pH of 10.0 or more either of which allows for an environment under which the active component (which is preferably sodium dodecyl sulfate) destroys infectivity. The composition may be added to blood, blood products, collagen, tissues and organs prior to transplantation. The composition also may be added to livestock feed to denature any prions in the livestock. Methods of denaturing infectious proteins are also disclosed which method can use but do not require higher temperatures and long period of exposure.
