US Patent:

6939944, Sep 6, 2005
Filed:

Dec 30, 2002
Appl. No.:

10/331516
Inventors:

George Joseph Kutsek - South Park PA, US
Assignee:

Eastman Chemical Company - Kingsport TN
International Classification:

C09F001/00
C09F001/02
C09F001/04
C08L089/00
US Classification:

530210, 530215, 524798
Abstract:

The invention relates to the inhibition of crystallization in rosin and rosin-based materials through the use of crystallization inhibitors. More specifically, the crystallization inhibitor is selected from the group consisting of carboxylic acids and the salts of carboxylic acids. The invention also relates to the process of inhibiting crystallization in rosin and rosin-based materials.

US Patent:

20130225751, Aug 29, 2013
Filed:

Jan 14, 2013
Appl. No.:

13/740322
Inventors:

Eastman Chemical Company - , US
George Joseph Kutsek - South Park PA, US
John B. Penn - Pleasant Hills PA, US
Assignee:

Eastman Chemical Company - Kingsport TN
International Classification:

C09J 125/06
C08F 112/08
US Classification:

524505, 5253333, 524502, 524524, 524528, 524515
Abstract:

A low z-average molecular weight, high softening point polystyrene resin having a narrow molecular weight distribution, as well as methods of making and using the same, are provided. The use of an inert solvent and/or the order of addition of reactants during polymerization may contribute to the unique properties of the final homopolymeric resin. The polystyrene resin can be partially or fully hydrogenated and may have particular use as a tackifying agent in a variety of hot melt adhesive and rubber compositions.
