摘要:

Nitrile barrier polymers have as their largest potential market, and the initial target of the first producers, the soft drink and brewing industries. As containers for carbonated beverages, nitrile barrier polymers provide significant advantages over glass bottles: they have break resistance approaching that of metal cans, are lighter than a comparable capacity steel can, and are only slightly heavier than an aluminum can. Given these advantages plus transparency to allow inspection of contents, break resistance, a negligible injury hazard, light weight, and barrier properties providing normal shelf life for the product contained, bottles made from nitrile polymers are projected to make major inroads in the packaging of carbonated beverages, although recent Food and Drug Administration (FDA) actions have temporarily halted commercial activity.

摘要:

The flammability of plastics systems became a significant consideration for industrial formulators as legislation and fire regulations began coming into prominence in the mid- and late 1960s. As the mass of legislation grew, the number and variety of flame tests increased. Along with the increasing number and complexity of the flame tests, the science of flame testing began to develop.

摘要:

Monodisperse proteins and polydisperse carbohydrates and polyenes occur in nature. The proteins are random copolymers, but no block or graft copolymers occur in nature.

摘要:

Epoxies are utilized by the aerospace industry primarily in the form of matrices for composite materials and as adhesives. The increasing use of epoxies requires a knowledge of their lifetimes in extreme service environments. When epoxy adhesives and composites are utilized in primary structural components of airframes, it is vital that the durability of such components be known during design development. A number of laboratory and field studies have indicated that the combined effects of sorbed moisture and thermal environment can cause significant changes in the mechanical response of these materials [1, 2]. However, the long-term, in-service durability of epoxy adhesives and composites in primary structural airframe components is unknown primarily because (1) long-term, in-service aging characteristics are difficult to simulate by short-term laboratory and/or field tests, and (2) the basic phenomena responsible for the changes in the mechanical response in laboratory-simulated service environments have not been identified and/or understood.
