Document Type and Number:
Japanese Patent JPH06500812
Kind Code:
A
Abstract:
Improved flame retardant polymer latices are disclosed which comprise copolymers of ring-halogenated aromatic monomer units and alkyl acrylate/methacrylate monomer units, and which may additionally include at least one other monomer. In a first embodiment, the latices include ring-brominated aromatic monomer units and alkyl acrylate and/or alkyl methacrylate monomer units. In a second embodiment, the latices include these first two types of monomer units and further include third monomer units from unsaturated esters of saturated carboxylic acids, halogen-free aromatic monomers or unsaturated carboxylic acid monomers. In a third embodiment, the latices include four monomer units, namely ring-brominated aromatic monomer units, alkyl acrylate/methacrylate monomer units, halogen-free aromatic monomer units and unsaturated carboxylic acid monomer units. In one aspect, the halogenated aromatic monomers are present in an amount to provide from 7 to 20 weight percent bromine in the final latex composition. In another aspect, the halogenated aromatic monomers include polybrominated monomers, particularly to provide monomers having an average of at least about 1.5 bromines per monomer unit.
