Epoxidized soybean rubber

Two epoxidized triglyceride oils, vemonia oil (VO) and ESO, which have similar molecular structures and molecular weights but different polarities and functionalities, were used to prepare two liquid rubbers vemonia rubber (VR) and epoxidized soybean rubber (ESR). Both rubbers were prepared by pre-... 

Chem. Descrip. Epoxidized soybean oil CAS 8013-07-8 EINECS/ELINCS 232-391-0 Uses Plasticizer for coatings based on PVC and copolymers, PS, NC, chlorinated rubber and paraffin stabilizer for materials with acid-producing components... 

Rubber Seed Oil Rubber seed oil (RSO), which has a high C18 3, n-3 content (6), has a lower alcoholysis rate than linseed oil, but a higher alcoholysis rate than soybean oil and melon seed oil (165). Studies on the epoxidation of RSO by peroxyacetic acid generated in situ have shown that increase in the process temperature increases the rate of epoxide formation (166). The optimum alcoholysis temperature for RSO is 245 2°C. 

Epoxidizedsoybean oil (ESO) is produced via conversion of the double bonds of soybean oil with peracids or peroxides, resulting in more reactive oxirane or epoxide moieties, promoting chemical reactions [230-232]. ESO is normally used to plasticize and/or stabilize poly(vinyl chloride) (PVC), chlorinated rubber, and PVOH emulsions [231, 232]. The effects of ESO as a PLA plasticizer were reported elsewhere [230, 233, 234]. In summary, ESO lowered Tg, cold crystallization temperature Tm. enthalpy of cold crystallization (AHcc), tensile strength, and tensile...
