- FIG. 1 AFM images in sample tapping mode after rapid evaporation of dichloromethane.
- (a) copolymer D (b) copolymer C
- (c) copolymer B (d) copolymer A.
- FIG. 2 AFM images in tapping mode of the samples after annealing at 115 ° C. for 90 minutes.
- Figure 3 Stress-elongation curves of non-annealed samples for a tensile speed of 1 mm / min. Suppliers:
- Dihydroxytelechelic poly (methyl ricinoleate) (3) was synthesized by transesterification of methyl ricinoleate (1) in the presence of 1,3-propanediol as well as Ti (OBu) 4 .
- the methyl ricinoleate (1) used was previously purified on a chromatographic column using as eluent a heptane / acetone mixture (v / v: 98/2).
- the product (1), after purification, has a purity of 99% after analysis by gas chromatography.
- L-lactide (4) previously recrystallized from toluene, was introduced into a three-necked flask and then dried under dynamic vacuum for 12 h. In parallel, the previously prepared compound (3) was also dried under dynamic vacuum at 70 ° C. for 12 hours. Anhydrous toluene was then added to the flask containing the macro-initiator as well as to the flask containing the compound (4). The catalyst, tin octoate, was added to the solution of the compound (3) and then the mixture was stirred for 1 hour. This solution was then added to the L-lactide solution (4) and the reaction mixture was stirred vigorously under reflux at 140 ° C. for 4 hours.
- WPLLA mass percentage of the PLLA blocks derived from the compound (4) in the copolymer
- Tg glass transition temperature of the poly (methyl ricinoleate) block or PLLA in the copolymer
- Tf melting temperature of the PLLA blocks in the copolymer
- Xc crystallinity level of the PLLA blocks in the copolymer.
- DSC analyzes also confirmed the "block" structure of the copolymers due to the presence of two Tg, one to -70% corresponding to the poly (methyl ricinoleate) block (derived from compound 3) and another to ⁇ O'C corresponding to the two PLLA blocks (from compound 4).
- the melting temperature of the triblock copolymer (5) is similar to that of PLA alone, namely approximately 180 ° C. This also confirms the "block” structure of the copolymer. Indeed a statistical distribution of ricinoleate units in the polymer would have led to a significant decrease in the melting temperature.
- the block polymers were dissolved in dichloromethane and then deposited by spin-coating on silicon wafers.
- the films were then analyzed by atomic force microscopy (AFM) and the images revealed nano-organizations in lamellae, cylinders or spheres according to the proportion between the different blocks.
- AFM atomic force microscopy
- a large proportion of amorphous poly (methyl ricinoleate) block induces a clear orientation of the lamellae in a direction of space whereas the increase in size PLA blocks with respect to poly (methyl ricinoleate) lead to the formation of "terraces" characteristic of strong crystallization.
- the structure of spherulites has also been studied by light microscopy. A clear decrease in the diameter of the spherulites is observed when the percentage of PLA is increased. This means that there are more seed crystals and therefore the material has a higher crystallinity.
- Copolymers having 17% and 29% poly (ricinoleic acid) break for respective elongations of 98% and 95% This strategy to limit the brittle nature of the PLLA by incorporation of soft segments of low Tg could thus be validated by the mechanical tests.
- the castor (6) methyl esters (1 eq.), The polypropylene glycol (PPG) (0.1 to 0.2 eq.), The catalyst Ti (BuO) 4 were loaded into the reactor.
- the medium was slowly heated under vacuum until the desired operating conditions (T: 200 ° C, P: 6 to 20 mbar) were reached.
- the reaction medium was maintained under these conditions for 6 h to 10 h.
- the medium was cooled and the vacuum was broken to give a limpid orange product which did not undergo any post-treatment.
- the polyricinoleate was synthesized according to the procedure of Example 2, and according to the specific conditions of Table 3 below.
- A represents the following group:
- a ternary mixture PLA / Poly (ricinoleic acid) / triblock copolymer (5) was made and studied.
- PLA / Poly ricinoleic acid
