Abstract

Light-decomposable thermoplastic articles consist of (a) 70-90 wt. % thermoplastic homo- or copolymer and (b) 10-30 wt. % copolymer contg. in polymer chain, 15-90 wt. %, w. r. t. copolymer wt., units having formula R1-C(-CH2-)-COOR2 (I) or H-C(-CH2-)-OOCR3 (II) (where R1 is H or 1-6C alkyl; R2 is acetyl- or benzoyl-substd. aryl-, alkylaryl- or alkoxyaryl and R3 may denote same as R2 or is Ph or alkylaryl in which the aliphatic chain may be substd. by one nitrile gp. and the aromatic gp. by one halogen, 1-3C alkyl or alkoxy gp.). Used for disposable packaging material. Disposing of packaging waste. Risk of migration of copolymer contg. (I) or (II) into packed material e.g. food, is very much smaller than when using compsns. contg. low mol. wt. additives to achieve photo-initiated decompsn.
