Description
This web page summarizes information in PubChem about patent US-4013511-A. This includes chemicals mentioned, as reported by PubChem contributors, as well as other content, such as title, abstract, and International Patent Classification (IPC) codes. To read more about how this page was constructed, please visit the PubChem patents help page.
Enzymes are convalently found to anionic or cationic hydrophilic polymeric carriers formed by essentially complete reaction of pendent anhydride groups of ethylene-maleic anhydride copolymer (EMA) with a diamine selected from the group consisting of hydrazine, P, P'-diaminodiphenylmethane and 1,6-diaminohexane to produce resins having pendent amine groups. The EMA-hydrazide and EMA- P,P'-diaminodiphenylmethane resins can be rendered cationic by reaction with N,N-dimethyl-1,3-propanediamine.
