Mechanistic Aspects of the Effects of Stress on the Rates of Photochemical Degradation Reactions in Polymers
Abstract This review examines the mechanistic origins of the effects of stress on the photochemical degradation rates of polymers. Recent studies have shown that tensile and shear stresses accelerate
Quantum-Chemical Calculation of the Effect of Stress upon Reactions in Polymers
Abstract The change of energy barrier of stretched model molecules is calculated using semi-empirical quantum-chemical method MNDO. The reactions studied include hydrogen abstraction from polyolefin
Oxidation of stressed polymers as studied by chemiluminescence
The oxidation of polyamide 6 film and injection moulded specimens of Polypropylene (PP), high density polyethylene (HDPE) and polyamide 6 (PA6) subjected to constant load has been studied with
Preliminary study of stress aided photodegradation of rubber
A study has been made of the photodegradation of a car tyre sidewall rubber exposed to ultraviolet irradiation while under tensile stress. Comparisons are made of the behaviour of the unprotected
Photodegradable plastics: end-of-life design principles
Abstract Photochemically degradable polymers and plastics are reviewed with an emphasis on the environmental and molecular factors that control the onset of degradation and the rate of degradation. A
Weathering of polymers: mechanisms of degradation and stabilization, testing strategies and modelling
The weathering of polymers is reviewed with attention concentrated on the mechanisms of degradation and stabilization, the methods of testing weatherability, and the predictive modelling of
Effect of stabilization on creep crack growth in high-density polyethylene
Polyolefins, particularly polyethylene, are known to fail via crack initiation and crack propagation when exposed to multiaxial long-term static stresses at elevated temperatures. Using concepts of


The Attack of Ozone on Stretched Rubber Vulcanizates. I. The Rate of Cut Growth
Experimental measurements are described of the propagation of a cut through a stretched rubber sheet under the action of an atmosphere containing ozone. It is shown that a well-defined rate of cut
Ozone Cracking and Protection of Rubber
Abstract Studies of the growth of single ozone cracks show that a critical severity of deformation is required for growth to occur. Above this deformation the rate of single crack growth is
The attack of ozone on stretched rubber vulcanizates. II. Conditions for cut growth
Experimental measurements are described of the conditions necessary for crack growth in an atmosphere containing ozone. It is proposed that a characteristic value of the tensile stress at the tip of
Mechanism of Exposure-Cracking of Rubbers. With a Review of the Influence of Ozone
Abstract “Exposure-cracking” is the fissuring which occurs when stretched rubber is placed in an atmosphere containing ozone, and is frequently wrongly described as “sun-cracking”. These cracks form
