Title: The Innovations of Erik G Tornqvist
Introduction
Erik G Tornqvist is a notable inventor based in Scotch Plains, NJ (US). He has made significant contributions to the field of elastomeric copolymers, particularly those involving butadiene and piperylene. With a total of 3 patents, his work has had a considerable impact on various industries, especially in automotive applications.
Latest Patents
Tornqvist's latest patents focus on stereoregulated copolymers of butadiene and piperylene. These elastomeric copolymers contain at least 50 mole percent butadiene and are characterized by a random distribution of monomer units enchained in a stereo-regulated manner. Key features of these copolymers include: (1) vinyl unsaturation pendant to the main polymer chain, which is equal to or less than 10 percent of the total unsaturation present in the polymer; (2) enchainment of at least 95 percent of the piperylene as the 1,2-trans and 1,4-trans-stereoisomers; and (3) selective enchainment of between 50 and 95 percent of the butadiene as the 1,4-trans-stereoisomer. These copolymers, prepared using an iodine-containing hydrocarbon-soluble catalyst system, can be compounded with other elastomers and various reinforcing agents. When vulcanized, they exhibit high tensile strength, extension, modulus, and abrasion resistance, making them particularly useful in automotive tire-tread compositions.
