Decanedioic acid. decanedioic acid (ˌdɛkeɪndaɪˈəʊɪk) n (Elements & Compounds) a white crystalline carboxylic acid obtained by heating castor oil with sodium hydroxide, used in the manufacture of polyester resins and rubbers and plasticizers.
Elastomeric material compositions obtained from castor oil and epoxidized soybean oil
Elastomers are formed from castor oil and / or ricinoleic acid estolides and a polyester formed from an epoxidized vegetable oil such as ESO and a polycarboxylic acid such as sebacic acid, optionally in the presence of a peroxide initiator, or include crosslinked reaction products derived from ricinoleic acid or castor oil estolides, epoxy group-containing compounds such as epoxy resins and / or epoxidized vegetable oil, epoxy hardeners such as polyamine and polycarboxylic acid hardeners, thermally activated free radical initiators such as peroxides, and optionally but preferably include fillers such as limestone or wood flour. The elastomers can be prepared using a two-step, solvent-less procedure at elevated or ambient temperatures. These predominantly "all-natural" elastomers have physical properties comparable to conventional petroleum-based elastomers and composites and exhibit good flexibility, resiliency, abrasion resistance and inertness to hydrolysis. The resulting elastomers display good mechanical strength and resiliency, are resistant to abrasion and hydrolysis, and can be processed into sheet materials, which makes them attractive as floor covering components.

Non-ortho-benzene medical soft polyvinyl chloride plastic and preparation method thereof
InactiveCN101215398ARich sourcesEasy to process and modifySurgeryDIETHYLENE GLYCOL ADIPATEPolyvinyl chloride
The invention provides a non-o-benzene-type medical flexible polyvinyl chloride plastic and a process for preparation, and the components and the parts by weight are that polyvinyl chloride resin 100 parts, plasticizing agent 10-90 parts, stabilizing agent 1-10 parts, auxiliary stabilizing agent 1-10 parts, lubricating agent 0.2-5.0 parts and anti-oxidant 0-2 parts. The plasticizing agent is one and several of adipic acid propanediol ester, adipic acid diglycol ester, decanedioic acid butanediol ester, decanedioic acid propanediol ester, or adipic acid butanediol ester. The invention solves the bad effect which is caused by the dissolving out of phthalandione (2- ethylhexyl acrylate). The invention has the advantages that the invention not only keeps rich source of PVC material, but also the invention is easy to be processed and modified, and the products which are modified have excellent bioavailability, and the invention is applied in one time use, which can avoid cross-infection and the like. And the invention lowers the effects to environment, which belongs to environment-friendly-type products, and the performance of the products meets the existing standard requirements.
