摘要：
Films of poly(vinylbutyral) (PVB) from two proprietary sources were tested for photochemical behavior upon exposure to UVB, UVA, BLB, and high-output '' daylight '' fluorescent (DLF) lamps. Discoloration and brittleness followed the buildup and subsequent decline of peroxide content. In the range of 60-89.9 degrees C, the onset of crosslinking and the loss of weight obeyed the Arrhenius relationship. At temperatures above the second-order-transition temperature, T-g, crosslinking predominated; at temperatures below T-g, chain breaking tended to prevail. (C) 2005 Elsevier Ltd. All rights reserved.
