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.

Tetraesters of a C-Caliphatic tetracarboxylic acid and OXO-alcohols and plasticized compositions containing said tetraesters are provided.

Tetracarboxylic ester plasticizers

Improved COsorbents comprised of a mesoporous silica functionalized with a polyamine are obtained by the in-situ polymerization of azetidine. Also included herein are processes utilizing the improved COsorbents wherein COis chemisorbed onto the polyamine portion of the sorbent and the process is thermally reversible.

Provided are compositions, processes for making, and processes for using triglycerides as plasticizers. Triglyceride plasticizers can be produced by recovery of linear or branched Cto Caldehydes from a hydroformylation product, oxidation to the acid with oxygen and/or air, recovery of the resulting acid, and esterification with 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. 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.

Triglyceride plasticizer and process of making

In a process for producing a functionalized polyalkenamer, at least one monomer comprising a monocyclic olefin having at least one pendant alkyl group bonded thereto, wherein the pendant alkyl group has at least two carbon atoms and is substituted with a polar moiety spaced by at least one carbon atom from the monocyclic olefin, is contacted with a polymerization catalyst under conditions effective to effect ring opening polymerization of the monocyclic olefin and produce the functionalized polyalkenamer.

Production of elastomeric functionalized olefin polymers

Disclosed is a selected type of copolymer composition comprising copolymers having units derived from ethylene and dicyclopentadiene (DCPD) co-monomers. Such copolymer compositions: a) have a DCPD-derived comonomer unit content of from about 25 mole % to about 45 mole %; b) have a Weight Average Molecular Weight, M, of greater than about 170,000; c) comprise amorphous material and have glass transition temperatures, T, of from about 8&#xb0; C. to about 129&#xb0; C., which also fit the equation T(in &#xb0; C.)&#x2267;[(mole % DCPD&#xd7;3.142)&#x2212;4.67]; and d) comprise no significant amount of crystalline polyethylene homopolymer or crystallizable polyethylene segments within the ethylene-dicyclopentadiene copolymers. Such copolymers can be readily derivatized by hydrogenation and/or epoxidation to provide polymeric materials suitable for use as engineering thermoplastics. Also disclosed are processes for preparing and optionally further derivatizing ethylene/dicyclopentadiene copolymers having the characteristics hereinbefore described.
