Use of recycled plastics in wood plastic composites - a review.
TL;DR: In this article, a detailed review about some essential properties of waste and recycled plastics, important for wood plastic composites production, and of research published on the effect of recycled plastics on the physical and mechanical properties of WPCs is presented.

Review: degradation-induced embrittlement in semi-crystalline polymers having their amorphous phase in rubbery state
TL;DR: In this article, the degradation-induced embrittlement mechanism in semi-crystalline polymers having their amorphous phase in rubbery state is reviewed and a simple relationship expressing the chemicrystallization yield for a given polymer structure is proposed.
Book ChapterDOI
Environmental degradation of polyethylene
TL;DR: In this article, the authors identified more than 200 different degradation products including alkanes, alkenes, ketones, aldehydes, alcohols, carboxylic acid, keto-acids, dicarboxyl acid, lactones and esters in thermo-and photo-oxidised polyethylene.
Journal ArticleDOI
Mechanism of degradation induced embrittlement in polyethylene
TL;DR: In this paper, the authors studied the embrittlement of polyethylene films in air at 80°C and 90°C, and proposed a chain scission mechanism to induce chemicrystallization.

Analysis of the nonvolatile oxidation products of polypropylene I. Thermal oxidation
TL;DR: In this article, a general oxidation mechanism for polypropylene is presented and the overall functional group distribution is found to differ from that found in a polyethylene sheet, which is an indication of the importance of an intramolecular backbiting process.

Infrared spectrophotometric studies on polyethylene. II. Oxidation
TL;DR: In this article, infrared spectrophotometric studies show that during these types of oxidation carbonyl groups are formed and the concentrations of the three types of carbon to carbon double bond groups present are altered.

The action of oxygen corona and of ozone on polyethylene
Glenn D. Cooper,Maurice Prober +1 more
TL;DR: In this article, the infrared spectra of low-density polyethylene (LDP) was analyzed and it was shown that the carbonyl groups are present in a relatively thin oxidized layer, estimated to be between 5 X 102 and 7 X 104 A. in depth.
