A process for epoxidation of an unsaturated polymer involves mixing an unsaturated polymer and a peroxy acid in an absence of solvent to produce an epoxidized polymer. The process may require no solvent, require no catalyst, require no or little applied external heat input, require no applied cooling, require less epoxidation agent, be faster and/or result in more efficient conversion of the unsaturated polymer.

With the binder produced according to the invention, a number of coating products can be produced which adhere to plastics directly and without any chemical or physical pretreatment. Base coats, high-gloss lacquers, metallic lacquers, clear lacquers and effect lacquers can be produced which can be applied directly on plastics; this is an absolute novelty because pretreatment is no longer required. With the binder according to the invention it is also possible to formulate adhesives which guarantee very good bonding between plastics themselves and also paperboard packaging. The invention relates to the binder as well as base coats based on them, one-coat lacquers and adhesives.

A highly fire-resistant expanded polymeric material for thermal insulation, acoustic insulation and/or fire barrier contains rubber, expandable graphite, at least one alkaline earth metal component selected from alkaline earth metal carbonates, alkaline earth metal hydroxides, hydrates of either, and combinations thereof, and a component containing silica or a silicate. The expanded polymeric material is preferably manufactured by a process including decomposition of a chemical blowing agent.
