THERMOSETTING PHENOL-FORMALDEHYDE RESINS |
| 摘要 |
<p>Thermosetting pheno-formaldehyde resins having novel structures and properties are described. The resins are formed at a mole ratio of formaldehyde to phenol of above 1.7:1 in an aqueous reaction medium. The resins form acid-catalyzed, roomtemperature stable and mobile resins which may be applied as is onto substrates for the formation of molded articles, such as rice husk boards.</p> |
