Abstract: Copolymers of glycidyl acrylate and allyl glycidyl ether and terpolymers derived from addition of glycidyl methacrylate to the polymerizable mixture, having an inherent viscosity within the range of about 0.09 to 0.28 and an epoxy equivalent of at least about 0.64 per 100 g. of polymer are provided which upon admixture with a catalyst which is a radiation-sensitive aryldiazonium salt of a complex halogenide, provides compositions suitable for use in a dry photopolymer positive imaging process. In the process, the polymer which is non-tacky at room temperature, together with the catalyst is applied to a substrate and exposed to an energy source for example, electromagnetic radiation through a transparency or mask. Following exposure, the coating is heated to the softening point of the unexposed portion of the coating and a powder or toner is applied thereto, the toner being adhered to only the tacky, non-exposed area of the coating, resulting in a pigmented image.

Abstract: Lithium-initiated polymers are coupled with a vinylhalomethylarene such as vinylbenzyl chloride. Maximum molecular weight is obtained at about one mol of coupling agent for two mols of polymerlithium, indicating a major amount of the coupling to be in the form of about two polymerlithium entities being joined to one coupling agent. Excellent stability indicates little formation of branched polymer through carbon-lithium bonding. Consequently, the coupled polymer can be hydrogenated successfully to give a high molecular weight ozone-stable product.

Typically, a copolymer of ethylene and methyl acrylate is dissolved in a diarylalkane such as 1,1-dixylylethane. A transesterification catalyst and either isopropanol or tertiary butanol is added to the polymer solution which then is heated to reflux to convert the polymerized methyl acrylate moiety to the isopropyl or tertiary butyl acrylate moiety. Following completion of the transesterification reaction, any excess isopropanol or tertiary butanol is removed from the reaction system by distillation. The polymer solution then is heated to a temperature of the order of 320.degree. C to thermally crack the isopropyl or tertiary butyl acrylate and form the corresponding ethylene-acrylic acid copolymer. The ethylene-acrylic acid copolymer is insoluble in the diarylalkane and can be recovered by filtration.
