Zusammenfassung:	PURPOSE:To provide the subject polymer which consists of specific structural units, has a specified logarithmic viscosity, and is excellent is gas barrier properties and clarity. CONSTITUTION:The objective polymer consists of structural units of the formula (wherein R and R are each H or 1-6C alkyl; and R and R are each H or 1-6C acyl) and has a logarithmic viscosity of 0.3-4.0dl/g in a mixture (60/40 by wt.) of phenol and 1,1,2,2-tetrachloroethane.
