对甲基苯磺酸甲醛缩聚物的合成及性能

Synthesis and Behaviour of C-polymer of p-tulnenesulfate Aicid and Formaldehyde

合成了一类对甲基苯磺酸甲醛缩聚物 ,对其合成条件、结构、A2 、Mw、Tm及界面性能进行了分析。结果表明 ,在 95℃以 1 5 .7%的 98%硫酸催化下缩聚反应快 ,产率高。 p H值、温度对缩聚物水溶液的界面性能有较大的影响。

A C-polymer of p-tulnenesulfate acid and formaldehyde was synthesised. The polymer structure, A2, , Tm and interfacial behaviours were studied .It is made known that rate of condensation polymerisation was fast and rate of production was big at 95℃ using 98% H2SO4 as catalyst which quality percentage concentration was 15.7% in total polymerisation system,pH value and temperature had bigger effects on interfacial behaviours of water solution of C-polymer.
