R2 and R3 each represent a hydrogen atom or an alkyl group having a carbon number of at least 1 and no greater than 4. R2 and R3 are not the same as one another. When R1 represents a hydrogen atom, R2 and R3 are not bonded to one another. When R1 represents a methyl group, R2 and R3 are optionally bonded to one another to form a ring. r and s each represent a number greater than or equal to 0 and less than or equal to 49. t and u each represent a number greater than or equal to 1 and less than or equal to 50. r+s+t+u=100. r+t=s+u.
