LIGHT COLOR, LOW SOFTENING POINT PETROLEUM HYDROCARBON RESINS AND THE PRESSURE SENSITIVE ADHESIVES CONTAINING SUCH RESINS |
| 摘要 |
A light color petroleum hydrocarbon resin including an aromatic hydrocarbon component useful for tackifying block copolymers is described which has a softening point of about 0.degree.C to about 40.degree.C, a number average molecular weight (Mn) of from 350 to 600 and a molecular weight distribution (Mw/Mn) of from 1:1 to about 2.0. An adhesive comprising a copolymer and such resins. |
