Aliphatic long-chain C20 polyesters from olefin metathesis.
Self-metathesis of undecenoic acid with [(PCy3)2Cl2Ru=CHPh] (2), followed by exhaustive hydrogenation yielded pure 1,20-eicosanedioic acid (5) (>99%) free of side-products from isomerization. Polycondensation with eicosane-1,20-diol (6), formed by reduction of the diol, yielded polyester 20,20 (Tm = 108 °C). By comparison, the known ADMET polymerization of undec-10-enyl undec-10-enoate (7), and...
متن کاملLong-chain aliphatic polyesters from plant oils for injection molding, film extrusion and electrospinning
Dicarboxylic acids derived from plant oils are attractive intermediates for the synthesis of polymer materials. Similar to polyethylene, the incorporation of long methylene sequences enables polymer crystallization and renders polyesters hydrophobic. Long-chain aliphatic polyesters that incorporate the full length of the plant oil methylene sequences possess high melting points (Tm > 100 °C) an...
متن کاملLong-Chain Polyesters via Chemical Catalytic Conversions of Fatty Acid Esters
Plant oils with their long linear methylene sequences are attractive substrates for polymeric materials, such as long-chain aliphatic polyesters and polyamides. Existing biotechnological routes for their conversion to long-chain linear a,ro-dicarboxylic acid derivatives have recently been complemented by chemical catalytic conversions. This contribution discusses and compares the conversion of ...
متن کاملCalixarene-based molecular capsule from olefin metathesis
The reaction of tetra-kis-(all-yloxy)calix[4]arene with the first-generation Grubbs catalyst, followed by catalytic hydrogenation, gave the novel bis-calixarene 15,20,46,51,64,69,74,79-octa-oxatridecacyclo[32.28.8.8(3,28).1(13,53).1(22,44).0(9,14).0(21,26).0(38,70).0(40,45).0(52,57).0(59,63).0(7,80).0(32,73)]octa-conta-1(63),3,5,7(80),9(14),10,12,21,23,25,28(73),29,31,34,36,38(70),40,42,44,52,5...
متن کاملPhotolithographic olefin metathesis polymerization.
Patterning functional materials is a central challenge across many fields of science. The ability to lithographically fabricate micro- and nanostructures has been one of the most impactful technological breakthroughs of the last century. In part due to the complexity of the chemical processes in photoresists, there is a limited variety of materials that can currently be patterned by photolithog...
