A copolymer having the structure (I) wherein Q, Q, Q, Q, 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. 2. The copolymer of claim 1 , wherein the sum of m and n is 3 to 15.3. The polymer of claim 1 , wherein each occurrence of Qand Qis independently hydrogen claim 1 , methyl claim 1 , N claim 1 ,N-diethylaminomethyl claim 1 , N-ethylaminomethyl claim 1 , and phenyl claim 1 , provided that at least one of Qand Qis not hydrogen; each occurrence of Qis hydrogen; and each occurrence of Qis hydrogen claim 1 , methyl claim 1 , or phenyl.4. The copolymer of claim 1 , wherein each occurrence of Qand Qis independently methyl or N claim 1 ,N-diethylaminomethyl or N-ethylaminomethyl; and each occurrence of Qand Qis hydrogen.5. The copolymer of claim 1 , wherein m and n are each claim 1 , on average claim 1 , greater than zero.6. The copolymer of claim 1 , whereinthe sum of m and n is 3 to 15;{'sup': 1', '2, 'each occurrence of Qand Qis methyl or N,N-diethylaminomethyl or N-ethylaminomethyl; and'}{'sup': 3', '4, 'each occurrence of Qand Qis hydrogen.'}7. A composition comprising:{'claim-ref': {'@idref': 'CLM-00001', 'claim 1'}, 'the copolymer of ; and'}{'sub': 3', '8', '3', '8', '4', '16', '6', '12', '1', '3', '3', '6', '2', '6', '2', '6, 'a solvent selected from the group consisting of C-Cketones, C-CN,N-dialkylamides, C-Cdialkyl ethers, C-Caromatic hydrocarbons, C-Cchlorinated hydrocarbons, C-Calkyl alkanoates, C-Calkyl cyanides, C-Cdialkyl sulfoxides, and mixtures thereof.'}8. The composition of comprising claim 7 , based on the total weight of the composition claim 7 ,10 to 50 weight percent of the copolymer; and50 to 90 weight percent of the solvent.9. The composition of comprising claim 7 , based on the total weight of the composition ...
