Benzoyl Peroxide → Styrenemaleic anhydride

Participants

Reaction Steps

A styrene-maleic anhydride interpolymer is prepared by the following procedure. 176 parts of maleic anhydride are dissolved in 2641 parts of xylene. To this mixture at 105° C. is added first 188 parts of styrene. Then 1.83 parts benzoyl peroxide dissolved in 32 parts xylene are added over a 1.5 hour period. The mixture is maintained at 104°-106° C. for 4 hours, then is stripped to 150° C. at 200 torr. The resulting interpolymer has RSV of 0.25.
