Abstract
A polymer composition having satisfactory processing stability is provided which comprises a polymer; a bisphenol monoester represented by the Formula (1): 1 wherein R1 represents hydrogen, alkyl or phenyl group; R2 and R3 each independently represents alkyl group; and R4 and R5 each independently represents hydrogen or methyl group; and a bisphenol diester represented by Formula (2) 2 wherein R6 represents hydrogen, alkyl or phenyl group; R7 and R8each independently represents alkyl group; and R9 and R10 each independently represents hydrogen or methyl group in which amount of the compound of formula (2) is 0.001 to 5 parts by weight based on 100 parts by weight of the total amount of the compounds of formulae (1) and (2).
