Embodiment 1

[0158] The method described in Comparative Experiment 1 was used to prepare a multilayer polymer laminate with a "hard layer-soft layer-hard layer" structure (layer A / B / C), with the following differences. Layer A is formed of an ethylene-methacrylic acid copolymer containing 19% by weight of methacrylic acid, and is neutralized to a level of 37% by sodium ions. Layer B is formed of an ethylene-methacrylic acid-n-butyl acrylate terpolymer containing 9.6% by weight of methacrylic acid and 23.5% by weight of n-butyl acrylate, and is neutralized to a level of 52% by sodium ions. Layer C is formed of a copolymer that is substantially the same as the copolymer used for layer A. The flux of extruder A was controlled by adjusting the screw speed to 70.6 rpm. The flux of extruder B was controlled by adjusting the screw speed to 15.4 rpm. The flux of extruder C was controlled by adjusting the screw speed to 14.3 rpm. After passing through the three-roller set, the multi-layer polymer lamina...

Abstract

The present invention provides for certain multilayer polymeric laminates and high strength laminates produced therefrom. The multilayer polymeric laminates provide improved acoustic barrier properties of the high strength laminates of the present invention.

Description

[0001] References to related applications [0002] This application claims the priority of US Provisional Application Serial No. 60 / 755,336 filed on December 30, 2005, the entire disclosure of which is incorporated herein by reference. Invention field [0003] The invention relates to a multi-layer polymer laminate material and a high-strength laminate material prepared therefrom with improved sound insulation performance. Background of the invention [0004] Glass laminates for safety glass applications are characterized by high impact resistance and penetration resistance, while at the same time, they do not scatter glass shards when broken. The glass laminate is usually composed of a sandwich structure of two glass sheets or plates, and the two glass sheets or plates are joined together by a polymer film or an intermediate layer of the sheet placed between the two glass sheets. One or two glass sheets can be replaced by optically transparent rigid polymer sheets, such as polyca...
