GRANULER AV EN BELAGD SAMPOLYMER AV VINYLACETAT OCH ETEN, FOERFARANDE FOER DERAS FRAMSTAELLNING OCH DERAS ANVAENDNING SOM LIM. |
摘要 |
<p>The coextruded granules consist of a copolymer of vinyl acetate and ethylene coated by coextrusion with a polar thermoplastic polymer such as, for example, polymethyl methacrylate or a copolymer of ethylene and vinyl acetate. They are advantageously produced by extrusion drying of a moist coagulate of a copolymer of vinyl acetate and ethylene and in-line coextrusion coating with a polar thermoplastic polymer. The coextruded granules are not tacky, can be stored without any problems and can be employed as adhesives for coextrusion.</p> |
