Claims
- 1. Copolymer consisting of 30 to 65 mole percent of structural units having the formula: ##STR7## 5to 45 mole percent of structural units having the formula: ##STR8## and 10 to 60 mole percent of structural units having the formula: ##STR9## and having a number average molecular weight of 500 to 200,000.
- 2. The copolymer as claimed in claim 1 which consists of 40 to 60 mole percent of the structural units of formula (I), 5 to 45 mole percent of the structural units of formula (II), and 15 to 60 mole percent of the structural units of formula (III).
- 3. The copolymer as claimed in claim 1 which has a number average molecular weight of 500 to 50,000.
- 4. The copolymer as claimed in claim 7 which has a number average molecular weight of 500 to 50,000.
- 5. The copolymer consisting of acrylonitrile units, styrene units and para-isopropenylphenol units, the mole percent of para-isopropenylphenol being in the range of 10 to 60 percent based upon the moles of the monomeric components, the minimum mole percent of styrene and acrylonitrile being 5 percent and 30 percent, respectively, based upon the moles of the monomeric compounds, and the number average molecular weight of the copolymer being 500 to 200,000.
