| abstract |
The present invention provides novel aminoplast fixed, hindered phenol containing antioxidants which are useful as stabilizers for coatings and polymers such as polyethylene, polypropylene and the like to prolong the useful shelf life. Aminoplast fixed antioxidants have reduced non-volatility and increased compatibility with the unfixed precursors, such as can be prepared by reacting a hindered phenol with an alkoxy methyl-substituted aminoplast. |
