  Coupling of Propylene Oxide and Lactide at a Porphyrin Chromium(III) Center

  摘要：

  5,10,15,20-Tetraphenylporphyrin chromium chloride (TPPCrCl) with added [Ph3P-N-PPh3]Cl+ (PPN+Cl) selectively polymerizes lactide (l and rac) dissolved in neat propylene oxide (PO) to yield polylactide (PLA) terminated by the -OCHMeCH2Cl group. At 0 degrees C and below, rac-LA yields polymers highly enriched in isotactic tetrads (iii). At 25 degrees C, some stereoselectivity is lost as transesterification becomes significant, and at 60 degrees C and above, enchainment of PO leads to the formation of 3,6-dimethyl-1,4-dioxan-2-one by a backbiting mechanism. At 0 degrees C, after the enchainment of l-(S,S)-LA in neat (R)-(+)-PO, the formation of (3S,6R)-3,6-dimethyl-1,4-dioxan-2-one occurs, while at higher temperatures the ratio of (3S,6R)-3,6-dimethyl-1,4-dioxan-2-one to (3R,6R)-3,6-dimethyl-1,4-dioxan-2-one falls to 3:2.

  The invention relates to a method for making a polymer wherein during the polymerisation is incorporated in the polymer chain by ring opening polymerisation a cyclic (alkyl)acryloyl carbonate having the formula (4): wherein R 1 and R 2 each independently are hydrogen, methyl or ethyl. Preferable the polymer is an (alkyl)acryloyl polycarbonate such that at least one first monomer a cyclic (alkyl)acryloyl carbonate having the formula (4). The (alkyl)acryloyl polyester may be modified and used in biodevices.

  The present invention relates to a method for making a polymer wherein during ring opening polymerisation is incorporated into the polymer chain at least one cyclic (alkyl) carbonate monomer having the formula (1) wherein Y is optional and represents the residue of a sulfhydryl reacted group, X represents a functional group reactive with a sulfhydryl group, L=—[CH2]n with n=0-10, or L=−[CH2]p-S—S—[CH2]q with p and q are 0-5 or L=-[PEG]- with PEG is a group that comprises a —[CH2CH2O]m-group with m=1-200, and R2 is hydrogen, methyl or ethyl. Optionally a cyclic (alkyl) acryloyl carbonate, or other additional monomer A may be used as comonomer. The polymer may be formed into a polymer article, such as a polymer film, such as a coating and modified and/or cross linked, to a polymer or polymer article obtainable, and to a biodevice, their use, and to the cyclic (alkyl)carbonates.
