The present invention relates to the field of water-soluble or water-dispersible copolymers comprising at least one random copolymer comprising styrene, methacrylic acid, acrylic acid and butyl acrylate.

Water-soluble copolymer composition

The present invention relates to a (meth)acrylic polymer composition. In particular the present invention it relates to polymeric composition suitable for security glazing. The invention also relates to a process for manufacturing such a polymeric composition suitable for security glazing. More particularly the present invention relates to a bullet resistant (meth)acrylic polymer composition and relates also to a process for preparing such a bullet resistant (meth)acrylic polymer composition and its use in glazing.

(Meth)acrylic polymer composition its method of preparation and use

A new class of alkoxyamines, exhibiting improved stability on storage, especially in the presence of monomers and/or of solvent is described, particularly where the alkoxylamines are a new class of oligomeric alkoxyamines, which are obtained by addition of one or more monomeric entities to an alkoxyamine.

Oligomeric alkoxy amines

The present invention relates to an impact resistant (meth) acrylic polymer composition. In particular the present invention it relates to impact resistant polymeric composition suitable for glazing or lightning applications. The invention also relates to a process for manufacturing such a polymeric composition suitable for glazing or lightning applications. More particularly the present invention relates to an impact resistant (meth) acrylic polymer composition and relates also to a process for preparing such impact resistant (meth) acrylic polymer composition and its use in glazing or lightning applications.

The present invention relates to the field of copolymers which are water-soluble or water-dispersible at neutral pH or near-neutral pH, that is to say between 5.5 and 9.5, comprising at least one random copolymer comprising methacrylic acid, butyl acrylate, styrene and a monomer chosen from styrenesulfonic acid or salts thereof, vinylbenzoic acid or salts thereof, 2-acrylamido-2-methanesulfonic acid or salts thereof, N-vinylpyrrolidone, alone or in combination.

Water-soluble copolymer composition with neutral pH

The present invention relates to a process for the radical polymerization of alkoxyamines at low temperature, typically at temperatures as low as &#x2212;50&#xb0; C., in the presence of a nitroxide reducing agent or photoinitiator.

Low-temperature radical polymerisation of alkoxyamines

The present invention relates to a process for the radical polymerization of alkoxyamines at low temperature, typically at temperatures as low as &#x2212;50&#xb0; C., in the presence of a nitroxide reducing agent.

The present invention relates to a process for the radical polymerization of alkoxyamines at low temperature, typically at temperatures as low as &#x2212;50&#xb0; C., in the presence of a photoinitiator.

Transparent and impact-resistant crosslinked acrylic composition consisting of a brittle matrix (I) having a glass transition temperature of greater than 0&#xb0; C. and of elastomeric domains having a characteristic dimension of less than 100 nm consisting of macromolecular sequences (II) having a flexible nature with a glass transition temperature of less than 0&#xb0; C.
