- the impact resistance (Charpy impact strength) of the molded body is higher than that of the molded body of Comparative Example 4, and the surface glossiness of the molded body is higher than that of Comparative Example 2.
- the releasability of the molded body from the mold is good.
- the 5% thermal weight loss rates of Examples 3, 7, and 13 are all 3.8 or less, and the addition of the functional group-containing olefin polymer (C) and the olefin wax (D) leads to the resin composition. The heat resistance was not easily lowered.
- Examples 9 to 14 use a masterbatch containing a predetermined amount of functional group-containing olefin polymer (C) and olefin wax (D), and the molded product of Example 7 is the same as the molded product of Example 3. Although it is a composition, it turns out that surface glossiness is improved. Although this improvement mechanism is not limited, the olefin polymer (C) and the olefin wax (D) are kneaded in advance, and as a result, the affinity between the two is further increased. As a result, bleeding out of the olefin wax (D) is suppressed during molding. Is guessed.
- the graph of FIG. 1 shows the impact resistance (Charpy impact strength) of the molded body and the surface glossiness of the molded body of Comparative Example 1, Comparative Example 2, Comparative Example 4, and Example 3.

- the resin compositions of Comparative Examples 5 and 6 contain the functional group-containing olefin polymer (C) and the olefin wax (D); the resin composition of Comparative Example 5 has a functional group-containing olefin weight. Since the content ratio of the coalescence (C) is low, the surface gloss of the molded body is not increased, and the resin composition of Comparative Example 6 has a low content ratio of the wax of the olefin wax (D), so that the impact resistance is low. It has not increased.

オレフィンワックス(D)の第一の態様は、未変性オレフィンワックス(d)の酸変性オレフィンワックス(D1)でありうる。酸変性オレフィンワックス(D1)は、カルボキシル基および/またはカルボキシル誘導体基を有する。カルボキシル基および/またはカルボキシル誘導体基は、酸変性オレフィンワックス(D1)のいずれの部分に結合していてもよい。酸変性オレフィンワックス(D1)におけるカルボキシル基および/またはカルボキシル誘導体基の濃度は特に限定されないが、酸変性オレフィンワックス(D1)に対して、0.1~6meq/gの範囲が好ましい。0.1meq/gより低いと、樹脂組成物の剛性および耐衝撃性が十分に改善されないことがある。6meq/gより高いと、酸変性オレフィンワックス(D1)の熱安定性が低下することがある。
オレフィンワックス(D)の第二の態様は、未変性オレフィンワックス(d)のカルボジイミド変性オレフィンワックス(D2)でありうる。カルボジイミド変性オレフィンワックス(D2)は、未変性オレフィンワックス(d)とカルボジイミド基と反応する官能基を有する化合物とを反応させて、カルボジイミド基と反応する基を有するオレフィンワックス(d’)を得て;さらに、カルボジイミド基と反応する基を有するオレフィンワックス(d’)とカルボジイミド基含有化合物とを反応させて得られる。
カルボジイミド基と反応する官能基を有するオレフィンワックス(d’)をグラフト共重合により得る場合には、未変性オレフィンワックス(d)に、カルボジイミド基と反応する官能基を有する化合物と、必要に応じてその他のエチレン性不飽和単量体等とを、ラジカル開始剤の存在下でグラフト共重合する。カルボジイミド基と反応する官能基を有する化合物を、未変性オレフィンワックス(d)にグラフト変性させる反応条件は特に限定されず、溶液法、有機溶媒に溶解させる方法、溶融混練法等、従来公知のグラフト重合法を採用することができる。
カルボジイミド基と反応する官能基を有するオレフィンワックス(d’)は、オレフィンとカルボジイミド基と反応する官能基を有する化合物とをラジカル共重合することによって得ることもできる。オレフィンとしては、上述のグラフト主鎖となるポリオレフィン(d)を形成する場合のオレフィンと同一のものを採用することが可能であり、また、カルボジイミド基と反応する官能基を有する化合物も上述の通りである。ラジカル共重合は、従来公知のラジカル共重合法の条件を採用することができる。
-N=C=N- (1)
オレフィンワックス(D)の第三の態様は、未変性オレフィンワックス(d)の酸化オレフィンワックス(D3)でありうる。酸化オレフィンワックス(D3)は、未変性オレフィンワックス(d)を酸素含有ガスと接触させることにより得られる。酸素含有ガスは、純酸素(液体空気分留または水の電解によって得られ、酸素が不純物として含む程度の他成分を含んでいても差し支えない)であってもよく、純酸素と他のガスとの混合ガスたとえば空気、およびオゾンを含んでいてもよい。酸化オレフィンワックス(D3)は、カルボキシル基、カルボニル基および/または水酸基を有する。カルボキシル基、カルボニル基および/または水酸基は、酸化オレフィンワックス(D3)のいずれの部分に結合していてもよい。酸化オレフィンワックス(D3)におけるカルボキシル基、カルボニル基および/または水酸基の濃度は特に限定されないが、酸化オレフィンワックス(D3)に対して、0.1~6meq/gの範囲が好ましい。前記濃度が0.1meq/gより低いと、樹脂組成物の成形体の剛性および耐衝撃性が十分に改善されないことがある。前記濃度が6meq/gより高いと、酸化オレフィンワックス(D3)の熱安定性が低下することがある。
本発明の樹脂組成物には、本発明の目的および効果を損なわない範囲で任意の添加剤、たとえば臭素化ビスフェノール、臭素化エポキシ樹脂、臭素化ポリスチレン、臭素化ポリカーボネート、トリフェニルホスフェート、ホスホン酸アミドおよび赤燐等のような難燃剤;三酸化アンチモンおよびアンチモン酸ナトリウム等のような難燃助剤;燐酸エステルおよび亜燐酸エステル等のような熱安定剤;ヒンダードフェノール等のような酸化防止剤;耐熱剤;耐候剤;光安定剤;離型剤;流動改質剤;着色剤;滑剤;帯電防止剤;結晶核剤;可塑剤;発泡剤;軟化剤;充填剤;等を必要に応じてその有効発現量配合してもよい。
本発明の成形用樹脂組成物は、任意の種々の方法を利用して製造することができる。例えば、熱可塑性樹脂または熱硬化性樹脂から選択される少なくとも1種の樹脂(A)と、無機強化材(B)と、オレフィン重合体(C)と、オレフィンワックス(D)と、他の任意成分とを、同時にまたは任意の順序で、タンブラー、V型ブレンダー、ナウターミキサー、バンバリーミキサー、混練ロール、単軸或いは二軸の押出機などで混合する方法が適宜用いられる。
本発明の樹脂組成物は、それを成形することで成形体として用いることができる。成形の方法は特に限定されないが、例えば射出成形、押出成形および圧縮成形などにより成形され、意匠性と成形性の観点から射出成形が好ましい。

<酸価>
JIS K5902に従って測定した。

作製した試験片を、JIS K-7111に基づき、ハンマー重量2J、ハンマー回転周りのモーメント1.08N・J、ハンマー持ち上げ角度50°、衝撃速度2.9m/s、回転軸から打撃点までの距離0.23mの条件でシャルピー衝撃値を測定した。
(b)曲げ試験

(c)引張試験
作製した試験片を、JIS K-7162-1Aに基づき、荷重レンジ1000kg、試験速度500mm/min、つかみスパン115mmの条件で降伏・破断強度および伸びを測定した。
(d)表面光沢評価
作製した試験片(100mm×100mm×4mm)の60°反射率を、GLOSS METER GM-3D (MURAKAMI Color Lab.製)を用いて測定した。ゲート付近を裏表、計5点ずつ測定した平均値を算出した。
(e)金型離型性評価
射出成形機を用いてコップ型成形体(φ50×50×1.6mm)を作製した。金型剥離のため、成形品を4本の突き出しピンで突き出す際に、ヒビ、変形、コップ底突き抜け等破壊が目視で観察されなかったものを○、ヒビ、変形、破壊が目視で観察されたものを状態に応じて△~×とした。
(f)耐熱性評価
SII社製のTG-DTA7300を用い、空気流量200mL/分の下、アルミパンに乗せたペレット約10mgを10℃/分で700℃まで昇温したときの重量変化を測定し、5%熱減量温度は昇温によって重量が5%減量した温度を記録した。また5%熱減量率は樹脂(A)及び樹脂組成物の5%熱減量温度と、官能基含有オレフィン重合体(C)及びオレフィンワックス(D)の添加量から、下記式に基づいて算出した。熱減量率は、官能基含有オレフィン重合体(C)及びオレフィンワックス(D)を一定量添加した場合の、樹脂組成物の耐熱性の低下度合いを示す。つまり、熱減量率が少ないほど、官能基含有オレフィン重合体(C)及びオレフィンワックス(D)の添加による影響(耐熱性低下)が少ない。
