POLYETHYLENE REFTALATE CONTAINER AND COMPOSITIONS HAVING IMPROVED MECHANICAL PROPERTIES AND BARRIER PROPERTIES AGAINST GASES

摘要

1. A container comprising a polyester composition comprising a polyester, a plastic deformation regulator and a gas barrier enhancing agent, where the plastic deformation regulator comprises a compound whose chemical structure corresponds to formula I: where R, R, R and R are independently heteroatoms, a tetravalent carbon atom or a C-C divalent or trivalent hydrocarbon; where each heteroatom, tetravalent carbon atom or C-C divalent or trivalent hydrocarbon may be unsubstituted or substituted by one or more functional groups or one or more C-Hydrocarbyls which may be unsubstituted or may be substituted by one or more functional groups; where i, ii , iii, iv, v and vi independently of one another represent a single, double or triple bond; where, if i is a double bond, then ii and vi are single bonds; where, if ii is a double bond, then i and iii are single bonds; where, if iii is a double bond, then ii and iv are single bonds; where, if iv is a double bond, then iii and v are single bonds; where, if v is a double bond, then iv and vi are single bonds; where, if vi is a double bond, then i and v are single bonds; where vii may be a single bond, a double bond or not a bond and connects R and R; where m, n, o and p independently of each other may be 0 or 1; where, if m is 0, then the bonds ii and iii form a continuous single bond; where if n is equal
