Abstract
There is disclosed the preparation of a gradable polymeric composition by the chemical modification of a polymeric material such as a polymer or copolymer. The preparation comprises reacting in the presence of free radicals the polymeric material with a non-polymeric organic reagent having a structure which contains both a hydrocarbon residue and a polymeric material-degradation-sensitizing group.
Claims18
A process for degrading a polymeric composition, which process comprises reacting the polymeric material in the presence of a source of free radicals with a non-polymeric organic reagent R-X, wherein R is at least one aliphatic hydrocarbon group containing at least six carbon atoms and X is at least one polymeric material-degradation-sensitizing group, to produce said degradable polymeric composition, and subsequently exposing said composition to at least one natural environmental condition sufficient to degrade said composition.
