A polymer alloy is obtained by adding a hydrophobic compound (1) having a hydrophobic main chain and a functional group containing an active hydrogen atom and a bisoxazoline compound (2) shown by the following formula to a composition containing plural polymers incompatible with each other:
wherein D represents an optionally substituted alkylene group, cycloalkylene group or arylene group, R1, R2, R3 and R4 respectively represent a hydrogen atom or an optionally substituted alkyl group or aryl group. The compound (1) includes a compound having an aliphatic hydrocarbon group as a main chain, containing a carboxyl group and having a molecular weight of 10,000 or less (e.g. higher fatty acids). A compatibilizing agent as produced by reacting the compound (1) and an excess amount of the compound (2) can also be used.
