Abstract
Experiments show that the effects of outdoor aging on rubber‐modified thermoplastics can be reproduced by laminating a layer of a glassy polymer onto the surface of unaged specimens. This technique is used to study the effects of fracture temperature, specimen geometry, and polymer composition on the impact strength of aged HIPS and ABS. Aging reduces the energy of crack initiation, so that the impact strength is determined by the crack‐propagation energy, which is in turn governed by the nature and concentration of the rubber and by the fracture temperature.Keywords
