Abstract
A copolymer having the structure (I) wherein Q1, Q2, Q3, Q4, m, and n are defined herein. The copolymer can be formed by oxidative copolymerization of 2,4,6-trimethyIresorcinoI with a monohydric phenol. Also describes are a composition comprising the copolymer and a solvent, and a composition comprising the copolymer and a thermosetting resin.
Claims14
A copolymer having the structure
- wherein each occurrence of Q1 and Q2 is independently selected from the group consisting of halogen, unsubstituted or substituted C1-C12 hydrocarbyl provided that the hydrocarbyl group is not tertiary hydrocarbyl, C1-C12 hydrocarbylthio, C1-C12 hydrocarbyloxy, and C2-C12 halohydrocarbyloxy wherein at least two carbon atoms separate the halogen and oxygen atoms;
- each occurrence of Q3 and Q4 is independently selected from the group consisting of hydrogen, halogen, unsubstituted or substituted C1-C12 hydrocarbyl provided that the hydrocarbyl group is not tertiary hydrocarbyl, C1-C12 hydrocarbylthio, C1-C12 hydrocarbyloxy, and C2-C12 halohydrocarbyloxy wherein at least two carbon atoms separate the halogen and oxygen atoms;
- and m and n are independently 0 to 50, provided that, the sum of m and n is at least 3.
