    摘要: The present invention concerns a process for the softening of furs while at the same time taking the greatest possible care of the appearance of the hair. The process of this invention comprises contacting a fur with an acid aqueous liquor containing an acid protease from a fungus strain of the genus Rhizopus rhizopodiformis, said acid protease being effective in the pH range of from about 2.5 to 6.5.

    摘要: The invention relates to the manufacture of crystalline epoxide resins which exhibit a marked crystallite melt temperature. The formation of the crystallites is caused by molecule blocks which are derived from polyester-polycarboxylic acids, which contain aliphatic radicals in the chain. According to the invention, two aliphatic polyester-polycarboxylic acids (A and B) are reacted under very specific quantitative conditions with epoxide compounds which contain at least 2 epoxide groups and optionally with curing agents. The polyester-polycarboxylic acids A are purely n-aliphatic in character, whereas the polyester-polycarboxylic acids B are not. They contain radicals which are derived from dimerized mono- unsaturated or di- unsaturated fatty acids during the ester formation. These crystalline synthetic resins are particularly suitable for use as material for absorbing solar energy in solar energy collectors.
