Product 1

HCID 6811Phthalic Anhydride

Procedure

The procedures of Example 1 were repeated except that 38.2 g. of methylhexahydrophthalic anhydride (Example 2) and 61.2 g. of dodecenylsuccinic anhydride (Example 3) which was a maleinization product of propylene tetramer or butylene trimer, were employed, respectively, instead of 34 g. of phthalic anhydride, to give light yellow resins. The properties thereof are shown in Table 1.
