Laminates based on polyphenylene oxide and isotactic polystyrene - useful in scratch- and boil-resistant products, packaging, etc.

摘要

Laminate comprises >=1 layer A and at least one layer B. Layer A contains >20% of a polyphenylene oxide of formula (I): (where n=103-104). Layer B is prepared from a styrene polymer, opt. modified w.r.t. impact resistance, contg. >40% styrene monomer polymerised therein, and is specifically an isotactic polystyrene, alone or admixed with an atactic polystyrene. A further layer C composed of atactic polystyrene and opt. modified w.r.t. fracture toughness, may be present as a welding and sealing layer. The excellent props. of the individual components of the laminate are maintained by using them in the form of layers which are bonded together.
