Abstract: Electron beam positive resists are formed from terpolymers of (a) an alpha olefin, (b) sulfur dioxide, and (c) a compound selected from the group consisting of cyclopentene, bicycloheptene and methyl methacrylate. The terpolymers have the particular unexpected advantage of being resistant to cracking of the films.

Abstract: It has been discovered that the sensitivity of positive acting polymeric electron beam resists is increased by well over an order of magnitude by using polymers having a molecular weight of at least one million, thereby making it possible to reduce the required radiation to below 3 x 10 6 coulombs/cm2.

Abstract: 1,269,385. Electrophotographic element. INTERNATIONAL BUSINESS MACHINES CORP. 8 April, 1969 [8 April, 1968], No. 17992/69. Heading H1K. [Also in Divisions C2 and C3] An electrophotographic element includes a polymeric material of the formula wherein n >40 or wherein one of R 1 and R 2 is hydrogen, the other is C 1-4 alkyl and n>10. The polymers may be applied to a substrate of aluminium glass, paper, or plastics as an organic solvent solution or by melting the polymers and applying in the liquid state. Activators or electron acceptors, which increase the photoconductivity of the polymers, may be incorporated into the polymers.
