RUBBER COMPOSITION AND PNEUMATIC TIRE
European Patent EP3910018 B1 · Filed: 05/07/2021 · Published: 02/22/2023
Assignee:
GOODYEAR TIRE & RUBBER (Akron, OH 44316, US)
Inventors:
ISITMAN NIHAT ALI (US)
WASSEN MARINE SOPHIE FRANCOISE (LU)
HINTERLONG RONDA JANE (US)
A vulcanizable rubber composition for use in a tread of a pneumatic tire is disclosed. The rubber composition comprises, based on 100 parts by weight of elastomer up to 100 phr of a solution polymerized styrene-butadiene rubber; from 5 to 50 phr of a fatty acid monoester…………..
The whole key to this invention appears to be the fatty acid monoester. Note that even coumarone indene resins are claimed specifically. Terpene resins are lumped together as hydrocarbons.

Eduard, Pieter (Almere, NL)
Disclosed are compositions comprising dimeric decarboxylated rosins (DDCRs), methods for making them, and applications thereof. DDCR of purity from 50-100 wt. % is obtained by decarboxylating a dimeric rosin acid or by dimerizing a decarboxylated rosin, in the presence of a catalyst, ……………….
This is a new type of material from rosin that was dormant for a long time, with a lot of potential.
REINFORCED RUBBER CONTAINING SILYLATED TRIGYLCERIDE OIL
European Patent EP3705518 B1 · Filed: 03/03/2020 · Published: 02/22/2023
Assignee:
GOODYEAR TIRE & RUBBER (Akron, OH 44316, US)

CANTWELL KELSEY ELIZABETH (US)
PAPAKONSTANTOPOULOS GEORGE JIM (US)
The key here is the ability of silylated vegetable oils to help facilitate the dispersion of silica in tire compositions. This patent is an excellent discussion and review of the history of the development of silylation chemistry including mixing designs. It is also a reflection on the value Goodyear places on R&D. It is also a reminder to resin producers that chemists have so many variables to study that one truly good technology can come along and replace some other company’s prime technology.
