摘要： The present invention is related to novel preparative methods to a novel class of polymer network materials with a highly branched poly(glycidyl ether) (PGE) structure. Said polymer networks are prepared by a simple procedure involving cationic ring-opening polymerisation and the method is applicable to a wide range of glycidyl ether containing monomers. The method comprises either the step of homopolymerising at least one multi-topic glycidyl ether comprising at least three glycidyl ether groups or the step of copolymerising (A) at least one multi-topic glycidyl ether comprising at least three glycidyl ether groups with (B) at least one glycidyl ether component comprising at least one glycidyl ether group by ring opening polymerisation.

摘要： The present invention relates to an article consisting of or comprising a bidirectional shape-memory polymer (bSMP), the bSMP comprising: first phase-segregated domains (AD) having a first transition temperature (Tt,AD) corresponding to a crystallization transition or glass transition of the first domains (AD), second phase-segregated domains (SD) having a second transition temperature (Tt,AD) corresponding to a crystallization transition or glass transition of the second domains (SD), the second transition temperature (Tt,SD) being higher than the first transition temperature (Tt,AD), and covalent or physical bonds cross-linking the polymer chains of the bSMP, and in this way interconnecting the first and second domains (AD, SD), wherein the second phase-separated domains (SD) form a skeleton which is at least partially embedded in the first phase-segregated domains (AD), and wherein polymer chain segments of the bSMP forming the first domains (AD) are substantially orientated in a common direction, such that the bSMP is able to undergo a reversible shape-shift between a first shape (A) at a first temperature (Thigh) and a second shape (B) at a second temperature (Tlow) upon variation of temperature between the first and second temperature (Thigh, Tlow) driven by the crystallization and melting or vitrification and melting of the first phase-separated domains (AD) and without application of an external stress, with Tlow

摘要： The invention relates to a method for producing a programmed shape-memory polymer which assumes a first temporary shape and has at least two further stored, thermally retrievable shapes, to be specific at least a second temporary shape and a permanent shape, with the steps of (a) providing a shape-memory polymer, which comprises at least two switching segments (A, B), which are capable by phase segregation of respectively forming a switching phase with in each case a transition temperature (Ttrans,A, Ttrans,B), (b) deforming the shape-memory polymer into a shape corresponding to the first temporary shape at a temperature above the upper transition temperature (Ttrans,A), and (c) cooling to a temperature below the lower transition temperature (Ttrans,B), thereby fixing the first temporary shape. The method according to the invention provides a one-step programming method for a three-shape plastic.

摘要： The invention provides a surface-functionalised polymeric object (10), comprising: a bulk material (11) comprising a copolymer containing constitution units derived from a first comonomer and constitution units derived from a second comonomer, the first comonomer being selected from L-lactide and D-lactide and forming sequences of oligo(L-lactide) or oligo(D-lactide) in the copolymer; and a surface layer (12) disposed on a surface of the bulk material (11), the surface layer (12) comprising a functionalising species and at least one chain of poly(D-lactide) or of poly(L-lactide) covalently bound to the functionalising species, and at least one chain being different from the oligo(L-lactide) sequences or oligo(D-lactide) sequences contained in the copolymer; wherein the surface layer (12) is attached to the bulk material (11) via stereocomplexes formed between the poly(D-lactide) chain(s) of the functionalising species and the oligo(L-lactide) sequences contained in the copolymer or via stereocomplexes formed between the poly(L-lactide) chain(s) of the functionalising species and the oligo(D-lactide) sequences contained in the copolymer, respectively. The surface-functionalised polymeric object can be produced in a one-step procedure by coaxial electrospinning.
