Zusammenfassung:	1,038,694. Optical elements. RUTGERSWERKE AND TEERVERWERTUNGA.G. April 17, 1963 [May 3, 1962], No.15012/63. Heading G2J. [Also in Division C3] A transparent organic synthetic material having an index of refraction in the range of n D = 1. 5200 to 1. 5260, which is used for producing molded optical articles consists of a copolymerized mixture of diethylene glycol-bis-allyl carbonate with 30-40 parts by weight of triallylcyanurate and 2. 5 to 5.0 parts by weight of a monoethylenically unsaturated compound selected from the group consisting of styrene, alpha-methylstyrene and vinyl toluene calculated for 100 parts by weight of the total mixture.
