The Terpenes Limonene, Pinene (s), and Related Compounds: Advances in Their Utilization for Sustainable Polymers and Materials

M Winnacker - 2022

… With regard to terpene-based polyamides, terpene-based lactams for ROP are 
very interesting building blocks [185, 186]. For instance, polyamides derived from L-Menthone 
and from β-Pinene have been described (Scheme 10) [187,188,189,190,191,192,193] …

Emulsion concentrates of lipophilic compounds
United States Patent 11369108 B2 · Filed: 12/19/2016 · Published: 06/28/2022

Assignee:

Bayer CropScience Aktiengesellschaft (Monheim am Rhein, DE)

Inventors:

Peris, Gorka (Cologne, DE)

The present invention relates to new, solvent-based emulsifiable concentrates of agrochemical active compounds, a process for the preparation of these formulations and their use for the application of the active compounds contained.  The focus is on terpenes.  Some of the elements of this invention are being practiced commercially right now.  The companies practicing their technologies however are keeping their technology under wraps.  This makes it very difficult for potential rivals to develop their own technology.  However, there are opportunities for new inventions.  You just have to know where to look.  This technology could (and probably does) have much more potential than the marketplace realizes.

Rubber composition for tires, and pneumatic tires
United States Patent 11370899 B2 · Filed: 04/13/2018 · Published: 06/28/2022

Assignee:

SUMITOMO RUBBER INDUSTRIES, LTD. (Kobe, JP)

Inventors:

Yoshiyasu, Hayato (Kobe, JP)

The present invention provides a rubber composition for tires which provides a balanced improvement in ice performance, fuel economy, and abrasion resistance, and a pneumatic tire containing the rubber composition.  In effect this invention is an improvement in all three (3) of the properties of the performance triangle for tires, which is a rarity in the tire industry.

Chewing gums with cross-linked hydrocolloids and coupling agents
United States Patent 11350646 B2 · Filed: 09/30/2016 · Published: 06/07/2022

Assignee:

WM. WRIGLEY JR. COMPANY (Chicago, IL, US)

Inventors:

Liu, Jingping (Chicago, IL, US)

Compositions of chewing gum base that can include hydrocolloids and coupling agents are provided. Methods of making gum bases and chewing gum formulations are also provided. This is a good short read on making chewing gum and chewing gum that is easier to remove from surfaces.  Terpene resins are key ingredients in chewing gum bases especially the top- of the line grades.

TREATMENT COMPOSITIONS COMPRISING CERTAIN PLANT ROSIN MATERIALS
European Patent Application EP4019000 A1 · Filed: 12/14/2021 · Published: 06/29/2022

Assignee:

The Procter & Gamble Company (Cincinnati, OH 45202, US)

Tahon, Cedric Marc (B - 1853 Strombeek-Bever, BE)
Smets, Johan (B - 1853 Strombeek-Bever, BE)

This is a European patent application, which might or might not be granted.  It makes a fine disctinction between terms like “carrier”, “diluent” etc and “delivery system that enhances performance”.  There are many products on the market which could easily be described by terminology in this application.  What it does do is provide a lot of ideas for new products based on rosin chemistry.  We shall see.
