<P>PROBLEM TO BE SOLVED: To provide a composition of products of the solvolysis of ethylene/vinyl ester copolymers which has excellent productivity and melt moldability although two or more products of the solvolysis of ethylene/vinyl ester copolymers are blended. <P>SOLUTION: A process for producing the composition of products of the solvolysis of ethylene/vinyl ester copolymers includes a step for performing solvolysis of an ethylene/vinyl ester copolymer (A') and a modified ethylene/vinyl ester copolymer (B') containing a structure unit originating from an unsaturated compound having a specified hydroxyl group, alkoxy group, acyl group or a cyclic carbonate structure or a cyclic acetal structure in the same system to produce the composition of products of the solvolysis of the ethylene/vinyl ester copolymers containing an ethylene/vinyl ester copolymer solvolysis product (A) and a modified ethylene/vinyl ester copolymer solvolysis product (B) having a structure unit having two hydroxyl groups in a side chain. In the process, a content ratio (B')/(A') of the components in the solvolysis step is 1 or more and a mixed ratio (B')/(A') of the components is 50/50 to 1/99 by weight. <P>COPYRIGHT: (C)2011,JPO&INPIT |
