236 HIGH PERFORMANCE POLYMERS
amino-1,2,4-triazole, or 1-(3-carbomethoxyacryloyl)-
5-amino-1,2,4-triazole, is copolymerized with methyl
methacrylate or styrene.
The release of herbicides by hydrolysis depends on
the nature of the amide bonds [103]. For example, poly
[1-(4-vinylbenzoyl)-5-amino-1,2,4-triazole] exhibits
a high release, whereas poly[3-(4-vinylbenzoyl)-5-
amino-1,2,4-triazole] exhibits a low herbicide release.
9.6 Suppliers and Commercial
Grades
There are essentially no registered trademarks con-
cerning triazole polymers, at least in the United States.
In contrast, there are some trademarks with regard
to agricultural products. Tradenames appearing in the
references are shown in Table 9.5.
