摘要:
Crosslinked polymers are prepared by reacting mutually reactive side groups, comprising reacting polymer chains containing carbonyl side groups, optionally protected, and 1,2- or 1,3-diol side groups, optionally protected, in the presence of an acid catalyst, thereby forming crosslinking bridges between polymer chains. Crosslinked polymers are also prepared in which polymer chains are bonded together by a low molecular weight crosslinking agent.
摘要:
Aqueous binders for liquid coating agents which contain a film-forming, aqueous plastic dispersion and a crosslinking component can be stored in ready-to-use form and quickly harden after being processed into a coating, at room temperature or a temperature just slightly above, forming a hard, dry, crosslinkable film. The plastic dispersion is an emulsion polymer with polymerized units of an ethylenically-unsaturated, radically polymerizable monomer with an alkylene urea side group. The crosslinking agent contains at least two, possibly protected, aldehyde groups.

The invention relates to a heat-sealing system consisting of an olefin polymer or olefin copolymer A, a methacrylate copolymer B, a graft polymer AB that is composed of the aforementioned components, a polyester C and an optional polymer D or an optional polymer blend DA, in addition to a solvent or solvent mixture L. The heat-sealing system is characterised by a high heat resistance, excellent barrier properties and short sealing times in relation to various plastics and aluminium foil or PET film.

摘要:
A radiation-reflecting road marking, comprising: metal particles having a diameter of between 0.5-2.5 mm, wherein the metal particles are particles comprising aluminum, magnesium, zinc or an alloy thereof. Also, a method for producing the radiation-reflecting road marking, where the radiation-reflecting road marking is a cold plastic, by mixing components of a two-part system, if necessary, to form a mixture, applying the mixture to a road surface, and adding the metal particles and optionally glass beads during or directly after an application of the cold plastic to the road surface.

摘要:
The present invention encompasses an innovative concept for the marking of trafficways, more particularly roads. The application qualities and lifetime of these new markings are comparable with those of the prior art. The markings also possess properties comparable with those of the prior art in respect of night visibility, back-in-service time, and surface quality. An additional contribution of the markings of the present invention, however, is that they can be used to support modern driver assistance systems and autonomous driving. With this in mind, the present invention relates more particularly to road markings which, building on established systems, are equipped with additional reflection capacity for electromagnetic radiation, more particular for microwaves and/or infrared radiation.
