In using the following sections, these Important points should be considered: 1. The QYHV resin designation Is obsolete, reference to QYHV should now be read as QYGV. 2. The use of the QYOH series resins should be emphasized over use of the QYNM resins. 3. Where two or more UCC resins are listed as the nearest equivalents to a particular competitive resin, they are listed in order of preference. The varied end uses, different rheological responses to stabilizers, and other features make the listing of several UCC resin equivalents necessary.
