Definitions
- the present invention concerns plasticizers and vinylic polymer compositions, and in particular, poly ⁇ -caprolactone polymers ( ⁇ -PCL) and polyvinyl chloride (PVC) compositions having said plasticizers.
- ⁇ -PCL poly ⁇ -caprolactone polymers
- PVC polyvinyl chloride
- plasticizers for vinylic polymer compositions, such as PVC.
- plasticizers such as dioctylphtalate (DOP), adipates, such as dioctyl adipate (DOA) and trimellitates, and in particular trioctyl trimellitate (TOTM).
- DOP dioctylphtalate
- DOA dioctyl adipate
- TOTM trioctyl trimellitate
- DOP and TOTM in particular are widespread for their advantageous properties of mechanical strength and permeability to O2 and CO2. While perhaps being the most preferred of those plasticizers now available,
- DOP, DOA and TOTM nonetheless also possess several properties which are disadvantageous and desireable to eliminate.
- One such property is the tendency for those plasticizers to escape or be extracted from the plasticized vinylic polymer composition (by, for example, volatilization and evaporation). This is particularly problematic when the composition is used in applications where it is exposed to elevated temperatures, such as an insulating medium for wires and cables, or to lipids (in the case of medical blood bags).
- Other such properties are that they are not biodegradable and that they have a tendency to absorb the active ingredients (such as diazepam) present in various medications, a property which is particularly problematic where medical perfusion bags are involved.
- polycaprolactones capro-3 lactone and capro-4 lactone
- plasticized thermoplastic vinylic resins plasticized with a plasticizing amount of relatively high molecular weight, solid, linear polymers of lactones, including poly capro-3 lactone and capro-4 lactone copolymers.
- Derwent publications 84-265927/43 disclose compositions having grafted PVC/polycaprolactone copolymers.
- the former discloses a PVC obtained either by grafting vinyl chloride onto polycaprolactone or by grafting a mixture of vinyl chloride and another comonomer onto polycaprolactone.
- the latter discloses kneading of, inter alia, PVC with polycaprolactone. While both disclosures state that the average molecular weight of the PCL as being between 10-* and 10°, these polycaprolactones are essentially of a relatively high molecular weight.
- Derwent publication 88-230506/33 discloses modified polycaprolactones having relatively high molecular weights of 1000 - 55000.
- WO 94/11445 discloses polymeric compositions comprised of a structural polymer and at least one oligomer as a plasticizer.
- the structural polymer which may be PCL, has an average molecular weight of > 50000.
- the oligomer which has an average molecular weight of 2000 or less, is apparently an oligohydroxy-alkanoate (OHA).
- polycaprolactones having relatively high molecular weights crystallize rapidly into the polymer matrix causing an important loss in the plastification and a loss of transparency of the polymeric composition.
- polycaprolactones having a relatively high molecular weight as well as those having a relatively low molecular weight has proven problematic due to the tendency of polycaprolactones to give "plate out".
- a primary goal of the present invention is to identify and provide a plasticizer for vinylic polymer compositions, and in particular for PVC compositions, which does not crystallize rapidly into the polymer matrix, which does not give plate out and which avoids the disadvantages experienced with DOP, DOA and TOTM but which gives results which approximate those of DOP, DOA and TOTM.
- Another primary goal is to provide a vinylic polymer composition, and in particular a PVC composition, which includes the plasticizer.
- Still other goals are to provide a process for making the said composition plasticized with the said plasticizers and to provide for usage of the said compositions.

- the finished articles used for evaluation were prepared from the respective formulations 6-12 by blending in a Plastographe Brabender PL2000-6 mixer with a debit of 360 cc (170°C, 50 rpm, 10 minutes) and pressing (170°C) in sheets of 200 ⁇ m and 1 mm thick depending the evaluations.
- the measure of the dynamic viscosity of the compositions in their melted states was performed on an ARES rheometer (Rheometric Scientific) having 25 mm diameter plates arranged in parallel, one above the other. The samples were introduced between the plates and heated at 190°C for about 10 minutes.
- the lower plate was rotated (turned) at a frequency of about 10 ⁇ 1 rad/second until a strain of 10% was imposed.
- composition #6 (PVC/CAPA® 214): 7.2 10 4 Pa.s (Pascal. second)
- Composition #7 (PVC/CAPA® 214): 1.8 10 4 Pa.s (Pascal. second)
