Nanostructured alkene-carbon monoxide terpolymers: New materials via a pulse-feed-polymerization technique

CO/Alkene Copolymers as a Promising Class of Biocompatible Materials, 1. Examination of the In Vitro Toxicity

“…These substances are easily accessible by Pd II catalyzed strictly alternating copolymerization reactions of α ‐olefins and CO (Figure 1A, R 1,2 = H, CH 3 ) 1. The new alkene‐CO co‐ and terpolymers2 consist of polar carbonyl groups and the incorporated, diverse olefins. The nature of the side chains (R 1,2 ; Figure 1A) and skeletal chain units allow switching between polar and nonpolar behavior of the polymer materials.…”

Novel Linear and Branched Poly(1,4-ketone)-b-polyalcohol Block Structures through Control of the Catalyst Initiation Mechanism

“…Besides the elegant work of Keim and Fink in the 1980s and the recent success of Brookhart, the alternating CO/alkene copolymerization reaction provides still an excellent route to such polar structures. We reported recently on the first high molecular weight CO/propene copolymers and on CO/ethene-CO/propene multiple block terpolymers with interesting mechanical and surface properties, which added a new family of flexible and elastic polyketones to the long existing, highly crystalline CARILON and KETONEX thermoplastics.…”

“…We now changed the activating agent from methanol to ethylene glycol monomethyl ether (Me-EG) and reduced the polymerization time to 24 h. This resulted in a PCO material having M w = 1.4 × 10 5 (entry 1) . A further reduction to 20 min, however, gave a product of M w = 4.4 × 10 3 (entry 2), , providing a suitable material for MALDI−TOF characterization (Figure ).…”
