由共軛二烯化合物及芳香族烯基化合物所形成的嵌段共聚合物的氫化物,即氫化嵌段共聚合物,與聚烯烴樹脂、聚苯乙烯樹脂等非極性樹脂及乙烯-丙烯橡膠等非極性橡膠的相容性(compatibility)相對較高,故廣泛利用含有氫化嵌段共聚合物的各種組成物作為相容劑。 a hydrogenated product of a block copolymer formed of a conjugated diene compound and an aromatic alkenyl compound, that is, a hydrogenated block copolymer, and a nonpolar resin such as a polyolefin resin or a polystyrene resin, and an ethylene-propylene rubber Since the compatibility of non-polar rubbers is relatively high, various compositions containing hydrogenated block copolymers are widely used as compatibilizers.
然而,氫化嵌段共聚合物與聚對苯二甲酸乙二酯(Polyethylene terephthalate,PET)或丙烯腈/丁二烯/苯乙烯共聚合樹脂(Acrylonitrile-Butadiene-Styrene copolymers,ABS)、尼龍等極性樹脂的相容性低,故為了確保可耐使用的物性,必須對氫化嵌段共聚合物賦予極性基。例如於專利文獻1~專利文獻3中,揭 示了一種經胺基改質的氫化共軛二烯嵌段共聚合物及與該氫化共軛二烯嵌段共聚合物的聚合物合金(polymer alloy)。 However, hydrogenated block copolymers and polyethylene terephthalate (PET) or acrylonitrile/butadiene/styrene copolymers (ABS), nylon and other polarities Since the compatibility of the resin is low, in order to ensure physical properties to be used, it is necessary to impart a polar group to the hydrogenated block copolymer. For example, in Patent Document 1 to Patent Document 3, An amine-modified hydrogenated conjugated diene block copolymer and a polymer alloy copolymerized with the hydrogenated conjugated diene block are shown.

根據現有的製造方法,脫溶劑通常是藉由使中性的水蒸汽與聚合物溶液接觸的方法來進行。因此,具有特定基(藉由-SiR1R2R3等保護基保護N原子所得的基團)的氫化共軛二烯嵌段共聚合物藉由上述的脫溶劑步驟而脫除保護基。因此,於最終獲得的聚合物中,保護基對N原子的保護率變低。另外,一般認為 較佳為以此種方式脫除如此般的保護。 According to the prior art manufacturing method, the solvent removal is usually carried out by contacting neutral steam with a polymer solution. Therefore, the hydrogenated conjugated diene block copolymer having a specific group (the group obtained by protecting the N atom by a protecting group such as -SiR 1 R 2 R 3 ) is deprotected by the above-described solvent removal step. Therefore, in the finally obtained polymer, the protection ratio of the protecting group to the N atom becomes low. In addition, it is generally believed that such protection is preferably removed in this manner.
然而,其結果所得的氫化共軛二烯嵌段共聚合物的經時穩定性、與熱塑性樹脂等的複合時的加工性、複合後的聚合物合金的物性等性能不充分。尤其於將所得的共聚合物放置於濕熱環境下後,與熱塑性樹脂等混合而形成聚合物合金的情形時,所得的聚合物合金的物性並不滿足要求。 However, as a result, the properties of the hydrogenated conjugated diene block copolymer obtained over time, the workability at the time of recombination with a thermoplastic resin or the like, and the physical properties of the polymer alloy after the composite are insufficient. In particular, when the obtained copolymer is placed in a hot and humid environment and mixed with a thermoplastic resin or the like to form a polymer alloy, the physical properties of the obtained polymer alloy are not satisfactory.
相對於以上的現有的製造方法,根據本發明的製造方法,由於對含有氫化共軛二烯嵌段共聚合物B的反應液進行特定的脫溶劑步驟,故認為維持了由矽烷基保護率所規定的保護基對N原子的保護,結果最終所獲得的氫化共軛二烯嵌段共聚合物C的經時穩定性(例如熔融流率(Melt Flow Rate)成為標準)、與熱塑性樹脂等的複合時的加工性、聚合物合金的物性優異。例如,藉由使用含有氫化共軛二烯嵌段共聚合物C的樹脂組成物,可製造耐熱性、剛性、耐衝擊性、面衝擊性、拉伸斷裂伸長率、鏡面性(specularity)及層間剝離性等的平衡優異的成形體。 With respect to the above conventional production method, according to the production method of the present invention, since the reaction liquid containing the hydrogenated conjugated diene block copolymer B is subjected to a specific solvent removal step, it is considered that the protection ratio of the alkyl group is maintained. The protection of the N atom by the predetermined protecting group results in the stability of the hydrogenated conjugated diene block copolymer C finally obtained (for example, the Melt Flow Rate is standard), and a thermoplastic resin or the like. The workability at the time of compounding and the physical properties of the polymer alloy are excellent. For example, by using a resin composition containing a hydrogenated conjugated diene block copolymer C, heat resistance, rigidity, impact resistance, surface impact resistance, tensile elongation at break, specularity, and interlayer can be produced. A molded body excellent in balance such as peelability.
以下,對藉由本發明的製造方法所得的氫化共軛二烯嵌段共聚合物C加以說明。再者,本發明中所用的共軛二烯嵌段共聚合物A的詳細情況將於後述。 Hereinafter, the hydrogenated conjugated diene block copolymer C obtained by the production method of the present invention will be described. In addition, the details of the conjugated diene block copolymer A used in the present invention will be described later.

The content of the polar group containing a N atom is also referred to as "modified mass". Polar group containing N atom The details of the measurement conditions of the content (modified mass) are as described in the examples.
於氫化共軛二烯嵌段共聚合物C所具有的含N原子的極性基中,N原子的矽烷基保護率為70%以上,較佳為80%以上,特佳為90%以上。N原子的矽烷基保護率的上限值並無特別限定,例如為100%,另外即便上限值為99%左右亦無實用上的問題。 In the N-containing polar group of the hydrogenated conjugated diene block copolymer C, the N-alkyl has a decyl group-protection ratio of 70% or more, preferably 80% or more, and particularly preferably 90% or more. The upper limit of the decyl group protection ratio of the N atom is not particularly limited, and is, for example, 100%, and there is no practical problem even if the upper limit is about 99%.
再者,有時亦將含N原子的極性基簡單地表示為「極性基」。 Further, the polar group containing a N atom may be simply referred to as a "polar group".
N原子的矽烷基保護率是藉由下述式來表示。 The decyl group protection ratio of the N atom is represented by the following formula.
矽烷基保護率(%)=鍵結於含N原子的極性基中的N原子上的Si原子(個)/[鍵結於含N原子的極性基中的N原子上的Si原子(個)+鍵結於含N原子的極性基中的N原子上的氫原子(個)]×100 矽 alkyl protection ratio (%) = Si atom bonded to N atom in a polar group containing N atom / (Si atom bonded to N atom in a polar group containing N atom) + a hydrogen atom bonded to an N atom in a polar group containing a N atom (a) × 100
於保護基為烷基矽烷基的情形時,矽烷基保護率是藉由下述式來表示。 In the case where the protecting group is an alkyl decyl group, the decyl group protecting ratio is represented by the following formula.
矽烷基保護率(%)=鍵結於含N原子的極性基中的N原子上的烷基矽烷基(個)/[鍵結於含N原子的極性基中的N原子上的烷基矽烷基(個)+鍵結於含N原子的極性基中的N原子上的氫原子(個)]×100 矽alkyl protection ratio (%) = alkyl decyl group bonded to N atom in a polar group containing a N atom / alkyl decane bonded to N atom in a polar group containing a N atom a hydrogen atom on a N atom bonded to a polar group containing a N atom (a) × 100
矽烷基保護率可將氫化共軛二烯嵌段共聚合物C純化後,將氘代氯仿(deuterated chloroform)用作溶劑,於400 MHz下根據1H-核磁共振(Nuclear Magnetic Resonance,NMR)光譜來算出。 The alkylene group protection ratio can be obtained by purifying the hydrogenated conjugated diene block copolymer C, using deuterated chloroform as a solvent, and according to 1 H-nuclear magnetic resonance (NMR) spectrum at 400 MHz.

It is from 0.5 g/10 min to 100 g/10 min, more preferably from 0.5 g/10 min to 50 g/10 min. In addition, the details of the measurement conditions of MFR are as described in the examples. Since the above-mentioned copolymer has a high protection ratio of N atoms in a polar group containing an N atom, it is excellent in stability over time, and for example, the retention of MFR is high even after heating promotion.

(7)應力殘存率 (7) Stress residual rate
應力殘存率是藉由應力緩和試驗(彎曲應力)而求出。藉由三點彎曲試驗法(夾具寬度為81.6 cm),於23℃的溫度條件下以20 mm/min的速度,將樹脂組成物射出成形所得的厚度×長×寬=2 mm×40 mm×100 mm的平板狀試驗片彎曲直至變形達到18%為止並保持。其後,將賦予固定變形(constant strain)(變形18%)並開始保持的時間(0秒)設定為初期應力,測定500秒後的應力 變化。應力緩和率是以初期應力(0秒)/應力變化(500秒)的方式算出。 The stress residual ratio is obtained by a stress relaxation test (bending stress). By the three-point bending test method (clamp width: 81.6 cm), the thickness of the resin composition was formed by injection molding at a temperature of 23 ° C at a speed of 20 mm/min × length × width = 2 mm × 40 mm × The 100 mm flat test piece was bent until the deformation reached 18% and was maintained. Thereafter, the time at which the constant strain (deformation 18%) was given and the start of holding (0 second) was set as the initial stress, and the stress after 500 seconds was measured. Variety. The stress relaxation rate was calculated as the initial stress (0 sec)/stress change (500 sec).
(8)耐化學品性 (8) Chemical resistance
耐化學品性(耐溶劑應力開裂(solvent stress crack)性)是藉由彎曲片(bent strip)法來求出。自將樹脂組成物射出成形所得的試驗片中切出厚度×長×寬=2 mm×40 mm×50 mm的平板狀試驗片,於表面中切出非貫通切口,彎折而嵌入至專用的夾具中,以水將經調整為50℃的「泡之力」(商品名:獅王(Lion)股份有限公司製造)稀釋,放置於經調整為22%非離子系溶液的溶液中,以10個試驗片中5個發生開裂(50%破裂時間)的時間進行評價。 Chemical resistance (solvent stress cracking) is obtained by a bent strip method. A test piece having a thickness of × length × width = 2 mm × 40 mm × 50 mm was cut out from the test piece obtained by injection molding of the resin composition, and a non-penetrating slit was cut out from the surface, and bent and embedded into a dedicated one. In the jig, dilute the "bubble force" (trade name: manufactured by Lion Co., Ltd.) adjusted to 50 ° C with water, and place it in a solution adjusted to 22% nonionic solution to 10 Five of the test pieces were evaluated for the time of cracking (50% rupture time).
對作為成分(I)的實施例2中所得的氫化改質聚合物I-2、與作為成分(II)的聚對苯二甲酸乙二酯(商品名「RT523C」日本尤尼派(Unipet Japan)公司製造)分別藉由真空乾燥機(佐竹化學機械工業公司製造)使水分率減少至200 ppm以下後,以混合比例(質量基準)(I)/(II)=10%/90%,並利用40 mm φ雙軸擠出機(池貝公司製造)於270℃下加熱、混練而製成股線(strand),繼而利用造粒機(pelletizer)將上述股線切斷,藉此獲得經顆粒化的樹脂組成物。藉由除濕乾燥機(佐竹化學機械工業公司製造)將所得的顆粒於80℃下乾燥5小時後,利用射出成形機(日本製鋼所公司製造)於加工溫度270℃下進行成形而獲得物性評價用的試驗片。 Hydrogenated modified polymer I-2 obtained in Example 2 as component (I) and polyethylene terephthalate as component (II) (trade name "RT523C" Japanese Unicorn (Unipet Japan) (manufactured by the company), the moisture ratio is reduced to 200 ppm or less by a vacuum dryer (manufactured by Satake Chemical Industry Co., Ltd.), and the mixing ratio (mass basis) (I) / (II) = 10% / 90%, and The strands were heated and kneaded at 270 ° C using a 40 mm φ twin-screw extruder (manufactured by Chiba Corporation), and then the strands were cut by a pelletizer, thereby obtaining granules. Resin composition. The obtained pellets were dried at 80 ° C for 5 hours by a dehumidifying dryer (manufactured by Satake Chemical Industry Co., Ltd.), and then molded at a processing temperature of 270 ° C by an injection molding machine (manufactured by Nippon Steel Works Co., Ltd.) to obtain physical property evaluation. Test piece.
另外,為了測定成分(I)的加熱促進後的物性,將實施例中所得的成分(I)於經調整為溫度85℃、濕度90%的恆溫槽中放置3天後,使用放置後的成分(I)與上述同樣地獲得試驗片。 Further, in order to measure the physical properties after the heating promotion of the component (I), the component (I) obtained in the examples was allowed to stand in a thermostat adjusted to a temperature of 85 ° C and a humidity of 90% for 3 days, and then the components after the placement were used. (I) A test piece was obtained in the same manner as above.
於實施例1A中,如表4~表14所記載般變更調配成分的種類、混合比例及加工溫度,除此以外,與實施例1A同樣地進行操作,分別獲得樹脂組成物及試驗片。 In the same manner as in Example 1A, the resin composition and the test piece were obtained in the same manner as in Example 1A except that the type, the mixing ratio, and the processing temperature of the compounding components were changed as described in Tables 1 to 14.
使用以上所得的試驗片進行各種測定。將結果示於表4~表14中。 Various measurements were carried out using the test pieces obtained above. The results are shown in Tables 4 to 14.
例如,若於表4中將實施例3A及比較例1A~比較例3A比較,則可知以下情況。(1)只包含PET的成形體的耐衝擊性及拉伸斷裂伸長率差。(2)包含未改質氫化聚合物及PET的成形體的耐衝擊性、拉伸斷裂伸長率、鏡面性及層間剝離等物性差。(3)雖為氫化改質聚合物、但於本發明以外的條件下進行脫溶劑而獲得的矽烷基保護率低的聚合物,其經時穩定性差,故包含加熱促 進後的該聚合物及PET的成形體的各種物性差。相對於該等,(4)為氫化改質聚合物、於本發明的條件下進行脫溶劑而獲得的矽烷基保護率高的聚合物,其經時穩定性優異,故包含加熱促進後的該聚合物及PET的成形體的各種物性的平衡優異。 For example, when Example 3A and Comparative Example 1A to Comparative Example 3A are compared in Table 4, the following can be seen. (1) The molded article containing only PET has poor impact resistance and tensile elongation at break. (2) The molded article including the unmodified hydrogenated polymer and PET has poor physical properties such as impact resistance, tensile elongation at break, specularity, and interlayer peeling. (3) A polymer having a low alkylene group-protecting ratio obtained by performing solvent removal under conditions other than the present invention, which is a hydrogenated modified polymer, has poor stability over time, and therefore contains heat. The formed polymer and the molded body of PET have various physical properties. With respect to these, (4) is a hydrogenated modified polymer, and a polymer having a high alkylene group-protecting ratio obtained by performing solvent removal under the conditions of the present invention has excellent stability with time, and therefore includes the heat-promoted polymer. The polymer and the molded body of PET have excellent balance of various physical properties.
另外,若於表14中將實施例1K~實施例7K及比較例1K~比較例4K比較,則可知以下情況。(1)只包含PLA的成形體的降伏應變低,應力殘存率高,耐應力開裂性差。(2)只包含PE的成形體的降伏應變高,應力殘存率低,但耐應力開裂性差。(3)包含PLA及PE的成形體的降伏應變低,應力殘存率高,耐應力開裂性差。比較例的耐應力開裂性差。相對於該等,(4)包含氫化改質聚合物(及視情況不同進而包含改質聚烯烴)及PLA(PET)、PE的成形體的降伏應變高,應力殘存率低,耐應力開裂性亦優異。即得知,藉由在PLA(PET)與PE的合金材中添加本發明的氫化改質聚合物,可提高降伏應變,降低應力殘存率,耐應力開裂性大幅度地提高。耐應力開裂性為與降伏應變與應力殘存率(應力緩和)有關,降伏應變越高、應力殘存率越低,則耐應力開裂性越良好。另外,藉由氫化改質聚合物的調配量的最佳化、或與改質聚烯烴的併用,可改善耐應力開裂性。進而,亦可使用作為應力開裂改善而一直以來進行的添加乙烯系彈性體、LDPE、LLDPE的橡膠改質的方法。 Further, when Example 1K to Example 7K and Comparative Example 1K to Comparative Example 4K were compared in Table 14, the following would be known. (1) The molded body including only PLA has a low drop strain, a high residual stress rate, and poor stress crack resistance. (2) The molded body containing only PE has a high drop strain and a low residual stress rate, but is inferior in stress crack resistance. (3) The molded body including PLA and PE has low drop strain, high residual stress rate, and poor stress crack resistance. The comparative example has poor stress crack resistance. With respect to these, (4) a molded article comprising a hydrogenated modified polymer (and optionally a modified polyolefin) and PLA (PET) or PE has a high drop strain, a low residual stress rate, and a stress crack resistance. Also excellent. That is, by adding the hydrogenated modified polymer of the present invention to the alloy material of PLA (PET) and PE, the strain at break can be increased, the stress residual ratio can be lowered, and the stress crack resistance can be greatly improved. The stress crack resistance is related to the strain and the residual stress rate (stress relaxation). The higher the strain at break and the lower the residual stress rate, the better the stress crack resistance. Further, the stress crack resistance can be improved by optimizing the amount of the hydrogenated modified polymer or by using it in combination with the modified polyolefin. Further, a method of modifying a rubber in which an ethylene-based elastomer, LDPE, or LLDPE is added as a stress cracking improvement can be used.
