Problems solved by technology

[0003] Although suitable for many applications, many existing rosin esters do not have suitable properties for specific applications
In particular, many commercially available rosin esters are colored (e.g. yellow or tan) and exhibit poor oxidation stability

Abstract

Rosin esters are provided. The rosin esters can exhibit improved color (e.g., the rosin ester can have a neat Gardner color of 8.5 or less), improved oxidative stability (e.g., when 1000 ppm or less of an antioxidant is present in combination with the rosin ester, the rosin ester can exhibit an oxidative-induction time at 130 DEG C of at least 75 minutes), improved color stability (e.g., the rosin ester can exhibit less than a 10% change in neat Gardner color when heated to a temperature of 160 DEG C for a period of three hours), or combinations thereof. Also provided polymeric compositions comprising the rosin esters, as well as methods of making the rosin esters.

Description

Technical field [0001] This application mainly relates to rosin esters and methods of making and using them. Background technique [0002] Rosin esters, including rosin esters derived from polyols, have been known for more than 50 years (see, for example, US Patent No. 1,820,265 to Bent et al.). Rosin esters are generally composed of rosin (which is mainly an isomeric C called rosin acid 20 A tricyclic monocarboxylic acid) is formed by the reaction of an alcohol (for example, glycerol or pentaerythritol). The resulting rosin ester is used as an additive for various applications, including use as a tackifier in hot-melt and pressure-sensitive adhesives, a modifier for rubber and various plastics, and an emulsifier for synthetic rubber , The basic raw material of chewing gum, coating composition such as resin in traffic paint and ink, and sizing agent for papermaking. [0003] Although suitable for many applications, many existing rosin esters do not have the proper properties for ...
