Description
本發明關於乙烯-乙烯醇系共聚物樹脂組成物,更詳細而言,關於可獲得在高濕度下具有高阻氣性之薄膜的乙烯-乙烯醇系共聚物樹脂組成物。
乙烯-乙烯醇系共聚物之透明性、氧氣等之阻氣性、香味保持性、耐溶劑性、耐油性、機械強度等優良,並被成形為薄膜、片材、瓶等且廣泛地使用作為食品包裝材料、醫藥品包裝材料、工業藥品包裝材料、農藥包裝材料等各種包裝材料。
但是,乙烯-乙烯醇系共聚物在分子內具有較具活性之羥基,故容易受濕度之影響且影響大,於高濕度環境下,其阻氣性會顯著地降低。
就提高乙烯-乙烯醇系共聚物之阻氣性的乙烯-乙烯醇系共聚物薄膜而言,專利文獻1揭示一種乙烯-乙烯醇系共聚物薄膜,係使無機化合物均勻地分散於乙烯-乙烯醇系共聚物而成。
又,專利文獻2揭示一種遮蔽紫外線之薄膜,係藉由使氧化鋅超微粒良好地分散於乙烯-乙烯醇系共聚物,而透明性優良。
[先前技術文獻]
[專利文獻]
[專利文獻1]國際公開第2016/088862號
[專利文獻2]日本特開2004-91521號公報
但是,上述專利文獻1所揭示之薄膜係使無機化合物分散於乙烯-乙烯醇系共聚物來改善阻氣性,惟,其於高濕度下的阻氣性並未令人滿意,並要求更進一步的改善。
又,專利文獻2雖然提供於乙烯-乙烯醇系共聚物含有氧化鋅超微粒之薄膜,但並非以改善高濕度下的阻氣性作為課題,故於高濕度下的阻氣性不足,並要求更進一步的改善。
於是,本發明在如此的背景下,提供一種乙烯-乙烯醇系共聚物樹脂組成物,係於高濕度下的阻氣性,尤其於高濕度下的氧氣阻障性優良。
然後,本發明人們發現,藉由在乙烯-乙烯醇系共聚物樹脂組成物中含有特定的金屬化合物,則於高濕度下的阻氣性優良。
亦即,本發明之第1要旨為一種乙烯-乙烯醇系共聚物樹脂組成物,含有乙烯-乙烯醇系共聚物、及金屬化合物,且上述金屬化合物符合下述通式(1)。
Ma(OH)bAn- (2a-b)/n‧‧‧(1)

又,本發明之第2要旨為含有上述第1要旨之乙烯-乙烯醇系共聚物樹脂組成物的薄膜,此外,第3要旨為具有至少一層由上述第2要旨之薄膜構成的層之多層結構體。
本發明之乙烯-乙烯醇系共聚物樹脂組成物係含有乙烯-乙烯醇系共聚物、及金屬化合物,且上述金屬化合物符合上述通式(1)者。在符合上述通式(1)之金屬化合物的周圍存在有乙烯-乙烯醇系共聚物分子、水分子時,金屬化合物之層與層會剝離,且該微細的層狀結構單元會和乙烯-乙烯醇系共聚物以分子等級進行交互作用之結果,由該乙烯-乙烯醇系共聚物樹脂組成物構成的薄膜成為高濕度下中的阻氣性,尤其氧氣阻障性優良者。
上述金屬化合物之金屬換算含量相對於乙烯-乙烯醇系共聚物100重量份,為0.01~10重量份的話,製成薄膜時,可製成於高濕度下的阻氣性,尤其氧氣阻障性更優良者。
含有本發明之乙烯-乙烯醇系共聚物樹脂組成物的薄膜,可製成於高濕度下的阻氣性,尤其氧氣阻障性優良者。
上述薄膜在20℃、90%RH之條件下的透氧度為15cc.20μm/m2.day.atm以下的話,可製成於高濕度下的阻氣性,尤其氧氣阻障性更優良者。
具有至少一層由上述薄膜構成的層之多層結構體,可製成於高濕度下的阻氣性,尤其氧氣阻障性優良者。
以下,針對用以實施本發明之形態具體地進行說明,但本發明不限於此。
又,在本發明中,有時會將「乙烯-乙烯醇系共聚物」稱為「EVOH」。
本發明之EVOH樹脂組成物含有EVOH、及金屬化合物,且上述金屬化合物符合下述通式(1)。
Ma(OH)bAn- (2a-b)/n‧‧‧(1)
上述M表示金屬種,A表示價數為n-之羥基配位子以外的陰離子性配位子。惟,A排除O亦即側氧基配位子。n為1以上之整數,又,a、b為比0大的數字,且符合a/b=0.1~10。
以下,針對各構成成分進行說明。
[EVOH]
上述EVOH通常係可藉由使乙烯與乙烯酯系單體的共聚物即乙烯-乙烯酯系共聚物進行皂化而得的樹脂,且為非水溶性之熱塑性樹脂。上述乙烯酯系單體考量經濟方面,一般而言可使用乙酸乙烯酯。
乙烯與乙烯酯系單體之聚合法可使用公知的任意聚合法,例如使用溶液聚合、懸浮聚合、乳化聚合來實施,一般而言會使用以甲醇作為溶劑之溶液聚合。得到的乙烯-乙烯酯系共聚物的皂化也能以公知的方法實施。
以此方式製造的EVOH係以來自乙烯的結構單元與乙烯醇結構單元為主,且通常含有未皂化而殘存的些許乙烯酯結構單元。
上述乙烯酯系單體考慮市場取得性、製造時的雜質處理效率佳之觀點,具代表性可使用乙酸乙烯酯。其它乙烯酯系單體例如可列舉:甲酸乙烯酯、丙酸乙烯酯、戊酸乙烯酯、丁酸乙烯酯、異丁酸乙烯酯、三甲基乙酸乙烯酯、癸酸乙烯酯、月桂酸乙烯酯、硬脂酸乙烯酯、叔碳酸乙烯酯等脂肪族乙烯酯;苯甲

上述EVOH中的乙烯結構單元之含量可利用使乙烯酯系單體與乙烯進行共聚合時的乙烯之壓力來控制,通常為20~60mol%,宜為25~50mol%,為25~35mol%特佳。該含量過低時,會有高濕下之阻氣性、熔融成形性降低的傾向,相反地過高時,會有阻氣性降低的傾向。
另外,該乙烯結構單元之含量可基於ISO14663進行測定。
又,EVOH中的乙烯酯成分之皂化度可利用將乙烯-乙烯酯系共聚物進行皂化時的皂化觸媒(通常可使用氫氧化鈉等鹼性觸媒)之量、溫度、時間等來控制,通常為90~100mol%,宜為95~100mol%,為99~100mol%特佳。該皂化度過低時,會有阻氣性、熱安定性、耐濕性等降低的傾向。
該EVOH的皂化度可基於JIS K6726(惟,EVOH係使用均勻地溶解於水/甲醇溶劑而成的溶液形式)進行測定。
又,上述EVOH之熔體流動速率(MFR)(210℃,荷重2160g)通常為0.5~100g/10分鐘,宜為1~50g/10分鐘,為3~35g/10分鐘特佳。該MFR過大時,會有製膜性變得不安定的傾向,過小時,會有黏度變得過高而使熔融擠壓變得困難之傾向。
該MFR係EVOH之聚合度的指標,可利用將乙烯與乙烯酯系單體進行共聚合時的聚合起始劑之量、或溶劑之量來調整。

尤其,於側鏈具有1級羥基之EVOH就保持阻氣性同時二次成形性良好的方面較為理想,其中,宜為共聚合有含羥基之α-烯烴類而成的EVOH,為於側鏈具有1,2-二醇結構之EVOH特佳。
尤其,於側鏈具有1級羥基之EVOH的情況,來自具有該1級羥基之單體的結構單元之含量通常為EVOH之0.1~20mol%,為0.5~15mol%更佳,為1~10mol%特佳。
又,本發明所使用的EVOH也可為經胺甲酸酯化、縮醛化、氰乙基化、氧伸烷基化、醯化等「後改性」者。
此外,本發明所使用的EVOH也可為和不同的其它EVOH之混合物,該其它EVOH可列舉皂化度不同者、聚合度不同者、共聚合成分不同者等。
上述EVOH宜為EVOH樹脂組成物的主成分,EVOH相對於EVOH樹脂組成物整體之含量通常為80重量%以上,宜為90重量%以上,為95重量%以上特佳。另外,上限通常為99.99重量%。

以下,針對各方法進行詳述。
[(I)之方法]
上述(I)之方法係使含金屬之化合物在鹼存在下進行反應之方法。
上述(I)之方法所使用的鹼可列舉例如:鹼金屬或鹼土金屬之氫氧化物等。其中,考量和含金屬之化合物的反應性優良之方面,宜為鹼金屬之氫氧化物,為氫氧化鈉特佳。

使鹼溶解而成的溶液中添加使有機酸金屬鹽溶解而成的溶液並進行混合之方法,使用無機金屬鹽時,宜為於使無機金屬鹽溶解而成的溶液中添加使鹼溶解而成的溶液並進行混合之方法。
使上述含金屬之化合物及鹼溶解的溶劑若為可溶解含金屬之化合物及鹼者,則無特別限制,可列舉例如:水、甲醇、乙醇、1-丙醇、2-丙醇、1-丁醇、2-丁醇等碳數1~5之低級醇。它們可單獨使用或也可合併使用2種以上。其中,考慮後處理容易的觀點,宜為水。
使上述含金屬之化合物溶解而成之溶液中的含金屬之化合物之濃度通常為0.5~3mol/L,宜為1~2mol/L。
又,使鹼溶解於溶劑而成的溶液中的鹼之濃度通常為0.01~100mol/L,宜為0.1~30mol/L,為1~10mol/L特佳。
含金屬之化合物及鹼的濃度比起上述範圍過低的話,會有反應無法充分地進行之傾向。又,含金屬之化合物及鹼的濃度比起上述範圍過高的話,會有引起副反應之傾向。
上述含金屬之化合物與鹼的莫耳比率(含金屬之化合物:鹼)通常為0.5:2~2:0.5,宜為0.8:1.5~1.5:0.8,為0.9:1.2~1:1特佳。莫耳比率為上述範圍外的話,會有反應無法充分地進行之傾向。
又,使含金屬之化合物與鹼進行反應時的pH通常為4~9,宜為5~8。pH比起上述範圍過低時,會有反應無法充分地進行之傾向。又,pH比起上述範圍過高時,會有生成的金屬化合物分解之傾向。另外,pH的調整係利用使含金屬之化合物溶解而成的溶液或使含金屬之化合物分散而成的漿液與使鹼溶解而成的溶液之使用量來實施。
上述反應中的反應溫度通常為15~60℃,宜為20~40℃。反應溫度過低的話,會有反應無法充分地進行之傾向,反應溫度過高的話,會有含金屬之化合物因熱而分解而無法獲得作為目的之金屬化合物之傾向。
又,反應時間通常為0.5~5小時,宜為1~3小時,反應時的壓力在常壓實施即可。
上述反應後,能以沉澱物形式獲得金屬化合物。得到的金屬化合物也可直接使用,但宜利用清洗、粉碎操作等來將金屬化合物純化後使用。
[(II)之方法]
上述(II)之方法係將含金屬之化合物進行加熱來使其反應之方法。
上述(II)之方法通常係藉由攪拌使含金屬之化合物溶解而成的溶液同時進行加熱來實施。
使含金屬之化合物溶解之溶劑可使用上述(I)之方法所列舉之溶劑。其中,宜為水、醇類,為水與1-丙醇之混合溶劑特佳。
上述加熱條件係將溶液之溫度於通常20~100℃,宜為50~95℃,為70~90℃特佳的方式進行加熱即可。反應溫度過低的話,會有反應無法充分地進行之傾向,反應溫度過高的話,會有含金屬之化合物因熱分解而無法獲得作為目的之金屬化合物的傾向。
又,反應時間通常為0.1~100小時,宜為0.5~30小時,為1~10小時特佳,反應時的壓力以常壓實施即可。
上述反應後,能以沉澱物形式獲得金屬化合物。得到的金屬化合物可直接使用,也可利用清洗、粉碎操作等來將金屬化合物純化後使用。
一般而言,金屬化合物係指例如:金屬鹽、金屬氧化物、金屬錯合物、金屬單體或合金等,但利用上述各方法所得到的金屬化合物,係如上所述般具有前述化學式(1)表示之層狀結構單元以特定之面間隔而成為層狀之結構的金屬層狀化合物。因此據推測,在金屬化合物的周圍存在有EVOH分子、水分子時,會使金屬化合物之層與層剝離,該經剝離之微細的層狀結構單元和EVOH以分子等級進行交互作用之結果,可獲得優良的氧氣阻障性。
考慮高濕度下中的阻氣性,尤其氧氣阻障性優良的觀點,本發明之金屬化合物使用CuKα線以廣角X射線繞射進行測定時,宜於2θ=2~15°具有X射線繞射
之主峰部,於2θ=2~9°具有主峰部更佳,於2θ=3~8°具有主峰部特佳。上述範圍具有X射線繞射之主峰部時,金屬化合物和EVOH會進行交互作用,並使EVOH之極性變高,而為高濕度下之氧氣阻障性優良的原因。
考慮和EVOH之分子、水分子之交互作用的觀點,上述金屬化合物之層間距離(層與層之距離)宜為0.01~50nm,為0.1~30nm更佳。上述金屬化合物的層間距離可基於以X射線繞射法進行分析時之2θ=2~15°的範圍中強度最強之峰部的繞射位置,並由Bragg之公式進行計算。
考慮能以EVOH之分子等級進行交互作用之觀點,從上述金屬化合物剝離後之層狀結構單元的分子量宜為100~10,000,為200~2,000特佳。
又,考慮和EVOH之分子的交互作用之觀點,上述層狀結構單元宜為親水性。
此外,上述層狀結構單元宜在20℃、90%RH之環境下靜置1,000小時仍不會分解。
EVOH樹脂組成物中的金屬化合物之金屬換算含量相對於EVOH100重量份,通常為0.01~10重量份,宜為0.05~8重量份,為0.1~5重量份特佳,為0.2~3重量份尤佳。金屬化合物之含量過少的話,會有高濕度下的氧氣阻障性降低之傾向,金屬化合物之含量過高的話,會有製成薄膜等時白化而透明性降低之傾向。
另外,EVOH樹脂組成物含有多種不同金屬種的金屬化合物時,係令EVOH樹脂組成物所含的全部金屬化合物之合計量為含量。
又,上述金屬化合物之含量可利用使用了ICP-MS之標準添加法求得。
[其它成分]

上述M表示金屬種(metal species),A表示價數為n-之羥基配位子以外的陰離子性配位子。惟,A排除O亦即側氧基配位子。n為1以上之整數,又,a、b為比0大的數字,且符合a/b=0.1~10。
據推測符合上述通式(1)之金屬化合物所具有的層狀結構和EVOH會進行交互作用,並使EVOH之極性變高,可獲得高濕度下之氧氣阻障性優良的效果。
又,本發明中,考慮高濕度下中的阻氣性,尤其氧氣阻障性優良的觀點,使用CuKα線以廣角X射線繞射進行測定時宜於2θ=2~15°具有X射線繞射之主峰部,於2θ=2~9°具有主峰部更佳,於2θ=3~8°具有主峰部特佳。
上述使用CuKα線以廣角X射線繞射進行測定時,於2θ=2~15°觀測到的X射線繞射之主峰部宜為來自上述通式(1)之峰部。
另外,上述廣角X射線繞射係利用下述條件進行測定者。
[測定條件]
.使用設備:D8 DISCOVER(Bruker Japan公司製)
.檢測器:二維檢測器VANTEC-500(Bruker Japan公司製)
.電壓:50kV
.電流:100mA
.相機長度(camera length):100mm
.測定方法:反射法
.累計時間:30分鐘
.波長:CuKα線(Kα1、Kα2未分離)
.檢測器位置:2θ=10°
