Photoreactive polymer and method for preparing the same

Номер: US20120149848A1
Принадлежит: LG Chem Ltd

The present invention relates to a photoreactive polymer that comprises a multi-cyclic compound in a main chain, and a polymerization method thereof. Since the photoreactive polymer according to the present invention comprises a multi-cyclic compound having a high glass transition temperature as a main chain, the thermal stability is excellent, and since the mobility of the main chain is relatively high as compared to that of an additional polymer, a photoreactive group can be freely moved in the main chain of the polymer. Accordingly, it is possible to overcome a slow photoreactive rate that is considered a disadvantage of a polymer material used to prepare an alignment film for known liquid crystal display devices.

Composite semifinished products and mouldings produced therefrom and directly produced mouldings based on hydroxy-functionalized (meth)acrylates and uretdiones which are crosslinked by means of radiation to give thermosets

Номер: US20160023384A1
Принадлежит: EVONIK DEGUSSA GmbH

The invention relates to a process for producing storage-stable polyurethane prepregs and to mouldings (composite components) produced therefrom. The prepregs and, respectively, components are produced by mixing (meth)acrylate monomers, (meth)acrylate polymers, hydroxy-functionalised (meth)acrylate monomers and/or hydroxy-functionalised (meth)acrylate polymers with uretdione materials. Photoinitiators can also optionally be added. This mixture or solution is applied by known processes to fibre material, e.g. carbon fibres, glass fibres or polymer fibres, and is polymerised with the aid of radiation or of plasma methods. Polymerisation, e.g. at room temperature or at up to 80° C., gives thermoplastics or thermoplastic prepregs, and these can subsequently also be subjected to forming processes. The hydroxy-functionalised (meth)acrylate constituents can then be crosslinked with the uretdiones already present within the system, by use of elevated temperature. It is thus possible to produce dimensionally stable thermosets or dimensionally stable crosslinked composite components.
