    Abstract: Disclosed is the preparation of compositions which are blends of certain types of hydrogenated ethylene-dicyclopentadiene (E/DCPD) copolymers in combination with elastomeric polymers. An E/DCPD copolymer and an elastomeric polymer are co-dissolved in a common liquid reaction medium which is then subjected to hydrogenation conditions. These hydrogenation conditions serve to hydrogenate in-situ at least a portion of the residual double bonds of the E/DCPD copolymer component and possibly also eliminate any residual unsaturation which might be present in the elastomeric polymers. This combination of materials which has been hydrogenated in-situ can then be co-precipitated to form a polymer composition which can be molded into polyolefin materials of improved structural, thermal and mechanical properties with desirable impact resistance.

    Abstract: Provided are processes for making, and processes for using triglycerides as plasticizers. Mixed triglyceride plasticizers can be produced by recovery of linear or branched C4 to C13 aldehydes from a hydroformylation product, oxidation to the acid with oxygen and/or air, recovery of the resulting acid, and esterification with a crude glycerol, wherein the total carbon number of the triester groups is from 20 to 25 for greater than or equal to 45 wt % of the plasticizer. The product selectivity obtained from esterifying with crude glycerol is comparable to that of esterifying with pure glycerol. Such plasticizers can be phthalate-free and provide outstanding properties including a suitable melting or glass transition or pour point, low volatility, increased compatibility, and excellent low temperature properties in a range of polymeric resins.
