There is disclosed a photoreactive plastic composition degradable by ultraviolet radiation, the composition comprising an organic polymeric material having dispersed therein a degradation controlling amount of an additive system consisting essentially of at least one organic photosensitizer and at least one readily autoxidizable organic substance.

Photo-degradable polymer compositions

In accordance with this invention, a chemically convertible polymeric coating composition is applied to the surface of a glass substrate and subsequently converted to a crosslinked coating by the application of UV light or another form of energy. The polymeric coating composition contains at least three basic components:

Three-component polymeric coating for glass substrate

There is disclosed an environmentally degradable plastic composition comprising an organic polymeric material having dispersed therein at least one ethylenically unsaturated alcohol or ethylenically unsaturated ester derived therefrom as a readily autoxidizable organic substance.

Degradable plastic composition containing unsaturated alcohol or ester

There is disclosed an environmentally degradable plastic composition comprising an organic polymeric material having dispersed therein at least one amine compound as a readily autoxidizable organic substance.

Degradable plastic composition containing amine

There is disclosed an environmentally degradable plastic composition comprising an organic polymeric material having dispersed therein at least one trialkyl ortho ester as a readily autoxidizable organic substance.

Degradable plastic composition containing ortho ester

There is disclosed an environmentally degradable plastic composition comprising an organic polymeric material having dispersed therein at least one unsaturated wax as a readily autoxidizable organic substance.

Degradable plastic composition containing unsaturated wax

There is disclosed a degradable article made from photodegradable polymeric or plastic compositions comprising at least one organic polymer or copolymer and at least two different aromatic carbonyl photosensitizers.

Degradable article

There is disclosed a novel degradable plastic composition consisting of an organic polymeric material, said material having dispersed therein at least one organic derivative of a transition metal and at least one readily autoxidizable organic material.

Degradable plastic

In accordance with this invention, a chemically convertible polymeric coating composition is applied to the surface of a glass substrate and subsequently converted to a crosslinked coating by the application of UV light or another form of energy. The polymeric coating composition contains at least two basic components:

Protective polymeric coating for glass substrate

There are disclosed novel photodegradable polymeric or plastic compositions comprising at least one organic polymer or copolymer and at least two different aromatic carbonyl photosensitizers.

Composition and process

There is disclosed the preparation of a degradable polymeric material consisting essentially of an organic polymeric base containing a degradation-promoting amount of a partially degraded organic polymer. The organic polymeric base and the degradation-promoting additive may be derived from the same or different polymers. The invention is especially useful in controlling the environmental deterioration of plastics. The rate of deterioration is a function of the environmental conditions such as light, oxygen, and temperature; the concentration of the additive; and the chemical structure(s) of both the base and the additive.

Controlled environmental deterioration of plastics

There are disclosed novel degradable plastic compositions consisting essentially of an organic polymer containing at least one organic chelating agent. The agent is one which chelates metal so as to form a metal complex which acts to accelerate polymer degradation in the presence of oxygen, electromagnetic radiation, and/or elevated temperature. This invention is especially useful in the preparation of degradable packaging materials such as films, bags, containers, etc.

Environmentally degradable polymer compositions

There is disclosed a photoresistive plastic composition degradable by ultraviolet radiation, the composition comprising an organic polymeric material having dispersed therein a degradation controlling amount of an additive system consisting essentially of at least one organic photosensitizer and at least one organic derivative of a transition metal.
