ALKALI METAL SALTS OF CROSS-LINKED POLYMERIC MICROGELS AS NUCLEATING AGENTS FOR POLYETHYLENE TEREPHTHALATE MOULDING COMPOSITIONS |
摘要 |
<p>Nucleating agents for polyethylene terephthalate moulding compositions comprise alkali metal salts of carboxylic acid-containing polymeric microgel particles which are prepared by polymerising in aqueous emulsion a monomer mixture containing about 5 to 50 percent by weight of polymerisable carboxylic acid monomers, up to 10 percent of a multifunctional cross-linking monomer and one or more carboxyl-free relatively water-insoluble polymerisable vinyl monomers.</p> |
