PROCESS FOR THE PRODUCTION OF AUTOCROSSLINKABLE POLYMERS |
摘要 |
<p>A PROCESS FOR THE PRODUCTION OF AUTOCROSSLINKABLE POLYMERS Storable, autocrosslinkable polymers containing N-alkoxy-methyl groups are obtained by reacting 5-alkoxymethyl-1,3,4-dioxazol-2-ones with a polymer having an average molecular weight above 600 and an average of more than one Zerewitinoffactive hydrogen atom in the molecule in the presence of a catalytic quantity of at least an alkali metal salt. The new catalysts allow to carry out the reaction at a temperature in the range from 50.degree. to 110.degree.C and guarantee a complete reaction of the reactants into uncrosslinked but autocrosslinkable light-stable end products.</p> |
