In spite of developing new polymers and polymeric materials, only 40-60 are used commercially on a large scale. It has been estimated that half of the annual production of polymers is employed outdoors. Increasing the stability of polymers and plastics towards heat, light, atmospheric oxygen and other environmental agents and weathering conditions has always been a very important problem. The photochemical instability of most of polymers limits them to outdoor application, where they are photo- degraded fast over periods ranging from months to a few years. To the despair of technologists and consumers alike, photodegrada- tion and environmental ageing of polymers occur much faster than can be expected from knowledge collected in laboratories. In many cases, improved methods of preparation and purification of both monomers and polymers yield products of better quality and higher resistance to heat and light. However, without stabilization of polymers by applica- tion of antioxidants (to decrease thermal oxidative degradation) and photostabilizers (to decrease photo-oxidative degradation | | 出版日期 | Book 1990 | | 關(guān)鍵詞 | Compound; Lignin; Pigment; Polyolefin; Polyolefine; Polypropylen; additive; morphology; plastics; polyethylen | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-009-0747-8 | | isbn_softcover | 978-94-010-6821-5 | | isbn_ebook | 978-94-009-0747-8 | | copyright | Elsevier Science Publisher Ltd 1990 |
