The invention relates to an impact-modified molding composition, especially impact-modified PMMA, having an improved profile of properties, especially also at elevated temperatures, to molded articles obtainable therefrom and to the use of the molding composition and the molded article.

Impact-resistant molding material having an improved characteristics profile

The invention relates to a molding composition modified for impact resistance, in particular to impact-resistant PMMA with improved optical properties at elevated temperatures, to molded items obtainable therefrom, and also to the use of the molding composition and of the molded items.

PMMA provided with impact resistance and having improved optical properties

The present invention relates to a continuous or semi-continuous freeze coagulation process for aqueous polymer dispersions, wherein said process comprises a freezing step and a solid-liquid separation step and is further characterized in that it comprises the further step of admixing water and/or water vapor between the freezing step and the solid-liquid separation step.

Continuous or semi-continuous freezing coagulation method for aqueous polymer dispersions

The present invention relates to a process for preparing aqueous dispersions. The invention also relates to the formation of core-shell particles in aqueous dispersions. The core-shell particles are useful as impact-modifiers for poly(meth)acrylate moulding compositions.

Process for preparing aqueous dispersions

The present invention relates to a core-shell particle which has a core, a first shell and, where appropriate, a second shell, where: 

Core and shell particle for modifying impact resistance of a mouldable poly (meth) acrylate material

The invention relates to a moulding composition, comprising a) 50 to 99.9% by weight of a matrix composed of a thermoplastic polymer and b) from 0.1 to 50% by weight of a matting agent in the form of a (meth)acrylate copolymer dispersed in the matrix, characterized in that the matting agent is a (meth)acrylate copolymer which has been prepared from the following monomers,

Molding material containing a matting agent

The invention describes a novel impact modifier, built up from core-shell1- and shell 2, the core being capable of plastic deformation. Good mechanical properties were achieved using a small amount of impact modifier.

PMMA moulding compounds with improved impact resistance

The invention relates to a novel impact-resistance modifier, constructed from a core-shell 1 and a shell 2, whereby the core is plastically deformable. The invention is characterised by excellent mechanical properties obtained by a low content of impact-resistance modifier.

An emulsion polymer having at least three phases, adaptable as an agent for modifying the impact resistance of rigid thermoplastic synthetic resins such as polymethyl methacrylate, and consisting of
