<p>of the Invention An aqueous treating composition, treated glass fiber strands and glass fiber strand mat formed therefrom is provided thnat enables the production of glass fiber mat reinforced thermoplastic polymer having improved atampability. The aqueous treating composition has a combination of organic silane coupling agents, where one is a vinyl-containing organic silane coupling agent end the other is maturated amino-organic silane coupling agent. The amino silane coupling agent is present in an amount in the range of about 1 to about 40 weight percent and the vinyl-containing organic silane is present in an amount in the range of about 60 to about 99 weight percent, both amounts based on the amount of the combined silane coupling agents. The combined amount of the silane coupling agents is in The range of about 0.5 to about 10 weight percent of the aqueous treating composition. In addition there is present a heat stable organic peroxide a glass fiber lubricant and a nonionic surfactant. Optionally a film forming polymer and/or a softening agent can also be incorporated into the aqueous treating composition. Glass fiber strands treated with the aqueous treating composition can be processed into a continuous glass fiber strand mat that is needled and used to reinforce thermoplastic polymers such as polyolefins, polyamides, and polyalkylene terephthalstes.</p> |
