    摘要： The invention relates to a preformed sheet with an improved ballistic resistance, comprising a network of fibers having a tensile strength of at least 1.5 GPa, impregnated with at least 10% of a plastic material comprising a multiphase (meth)acrylic based polymer dispersion. Such polymer dispersion has a first phase which has a minimum glass transition temperature of at least 40° C. and a weight average molecular weight of less than 80,000 g/mol and a second phase having a maximum glass transition temperature of 30° C. or less and a weight average molecular weight of more than 100,000 g/mol.

    摘要： A process is described for making an aqueous coating composition comprising a cationic vinyl oligomer comprising the following steps: I. preparation of a cationic vinyl oligomer by solution or bulk polymerisation of components: i) 2 to 50 wt% of vinyl monomers bearing amine functional groups selected from the group consisting of non-ionic amine functional groups (a), permanent quaternary ammonium functional groups (b), neutralised amine functional groups (c) and mixtures thereof; and ii) 20 to 98 wt% of Ci to Ci8 alkyl (meth)acrylates; and II. dispersion of the cationic vinyl oligomer in an aqueous medium and neutralisation of non-ionic amine functional groups.
