A process for aftertreating tanned leather and pelts to impart a very soft and supple handle and good fullness to them, which comprises subjecting the leather or pelts to an aftertreatment with a polymer which is obtainable by (a) polymerising a monoethylenically unsaturated dicarboxylic anhydride...
Step 1: Understand Maleic AnhydrideMaleic anhydride is a compound that contains a double bond and can act as a dienophile in the Diels-Alder reaction. It is crucial to identify the structure of maleic anhydride, which has a cyclic anhydride structure with a double bond. Hint: Maleic anhydride...

1 is that the metal sp2Ãcarbon bond in theiene (8) be more stable than the cobalt sp2Ãcarbon bond in the cycloadduct (10).We had noticed this to be true on many occasions when we ran demetallations [8],i.e.cobalt-substituted cycloadducts (such as 10)contain-ing small amounts...
A process for making derivatized polymers of maleic anhydride containing maleamic acid and its corresponding cyclic imide repeat units, in alcohol solution, at a temperature of about 60-160 �C, during a reaction period of about 1-25 hours. The product is a polymer having a predetermined ...
What is claimed is: 1. A product of the group consisting of polyhydric alcohol partial esters of a polycarboxylic acid from a Diels-Alder adduct of maleic anhydride with an unsaturated carboxylic acid having a 10 to 25 carbon chain, and sulfonate derivatives thereof. 2. A product according ...
