1,183,693. Cross-linking by radiation. FIRESTONE TIRE & RUBBER CO. 8 Aug., 1968 [23 Aug., 1967], No. 38029/68. Headings C3E and C3P. A cross-linkable polymeric material is shaped in the uncured state, cooled so that it undergoes a second-order transition and is converted into a glass-like state, and while in this glass-like state it is cross-linked by exposure to radiation without effecting thermal distortion thereof. The process is particularly applicable to SBR and neoprene. By this means very intricate shapes can be cured without damage. |
