摘要:
The invention relates to aqueous polymer dispersions for composite film lamination and to a multiple-step method for the production of same from ethylenically-unsaturated, radically polymerisable monomers. In a first step, a first polymer is produced through radical emulsion polymerisation. In a further step, an aqueous polymer dispersion is produced in the presence of the first polymer. The monomers of the first step comprise monomers having acid functional groups. The monomers of the further step comprise monomers having oxazoline functional groups. The polymerisation of the first step occurs at low pH of less than 5. The acid functional groups of the first polymer are neutralised before the polymerisation of the further step. The aqueous polymer dispersions can be used as an adhesive for the production of composite films.

摘要:
It is described a flow medium (130) for assisting a resin (240) to be transferred into a mold (100, 105) accommodating a layered structure of reinforced material (120). The flow medium (130) is configured in such a manner that when the resin (240) is cured the flow medium (130) becomes incorporated within a final composite component comprising the reinforced material embedded within the transferred and cured resin (340). It is further described a semifinished product comprising such a flow medium (130) and a method for producing a composite component by utilizing such a semifinished product.
