Page/Page column 18, (2013/03/26)
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 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.

Phosphonate compounds of the formula STR1 wherein R is hydrogen or methyl, R1 is hydrogen, methyl or ethyl, and y is an integer from 0 to 2, are useful as flame retardants for thermoplastic polymers, especially linear thermoplastic polyesters.
