标 题:Polyalphaolefins made from dimer olefins obtained from branched c10 monoolefins using solid acid catalyst
发明人：MALINSKI THOMAS; GEE JEFFREY C; BISCHOF STEVEN M; KERNS SPENCER A; HILLIER JAMES; WEBSTER-GARDINER MICHAEL S
权利人:CHEVRON PHILLIPS CHEMICAL CO LP
摘要:Synthesis of polyalphaolefins by oligomerization of one or more branched C 10 monoolefins with a solid acid catalyst to form an oligomer product, followed by hydrogenation of a C 20+ olefin portion of the oligomer product to form the polyalphaolefins. The solid acid catalyst is selective to C 20 olefin dimers.

摘要:Certain linear alpha olefin (LAO) syntheses are selective and form a predominant LAO and minor amounts of other LAOs. The minor product LAOs have economic value, but they are difficult to separate from a selective LAO product stream because they are present in such small amounts. Product streams from a selective LAO synthesis and a non-selective LAO synthesis may be combined together to overcome this difficulty, namely through fractionating the combined product stream in a common distillation section. Methods for separating LAOs may comprise: combining a first product stream from a first LAO synthesis process and a second product stream from a second LAO synthesis process, in which the first LAO synthesis process is non-specific and forms a distributed plurality of LAOs and the second LAO synthesis process is specific and forms a predominant LAO and one or more minor product LAOs, and fractionating the combined product stream.

标 题:Crosslinkable UV absorbing agent for UV absorbing lens
发明人：HONG SHINN-GWO
摘要:A crosslinkable UV absorbing agent prepared by the following steps: (1) preparing a mixture of reactants comprising a UV absorbing compound (A) with multiple pendant hydroxyl groups and an unsaturated monoglycidyl compound (B) with both reactive glycidyl and vinyl groups; (2) mixing a base catalyst (C) with the mixture of reactants; (3) initiating a synthesis reaction of the crosslinkable UV absorbing agent under heating; and (4) recovering the resulting product after the synthesis reaction is completed. The crosslinkable UV absorbing agent is directly applicable in the lens formulation to replace conventional crosslinking agent and UV absorber used in the production of the soft contact lens without any purification or modification.
