(D) silicone oil

Silicone oils generally have a straight-chain molecular structure and are classified according to the type of organic substituent group bonded to the silicon atom and the degree of polymerization of the siloxane. This can be broadly divided into straight-chain silicone oils and modified silicone oils.

Straight silicone oil and its name means that the organic chlorosilane produced by the direct method is oiled by the hydrolysis polymerization process as it is, and the modified silicone oil is a process for reacting other organic substances in the process of making oil from the organic chlorosilane .

Silicone oils are generally referred to as dimethylsilicone oils in which all of the substituents are methyl groups. The dimethylsilicone oils are colorless transparent, tasteless and odorless, ranging from low viscosity oils such as water to high polymeric materials which are the base of the silicone rubber, depending on the degree of polymerization. Such linear silicone oil also includes methylphenylsiloxane having a phenyl group introduced into a part of the substituent. Methylphenylsiloxane with phenyl groups, diphenylsiloxane, and copolymers of siloxane and diphenylsiloxane. When the content of the phenyl group is small, the low temperature coagulation point of the oil is low, and when the content is high, the thermal oxidation stability can be improved than that of the dimethylsiloxane alone.

The silicone oil in which a part of the substituent is introduced with an organic group other than the methyl group is referred to as a modified silicone oil. Examples thereof include organic groups containing a chloropropyl group, a phenylethyl group, a long chain alkyl group, a trichloropropyl group, an epoxy group, a cyano group and the like. This is an oil superior in lubricity to dimethyl silicone oil and is known as an oil excellent in paintability because it improves affinity with various organic materials.

The silicone oil may be used in an amount of 0.1 to 10% by weight, for example, 0.2 to 7% by weight or 0.2 to 5% by weight based on the total weight of the polyarylene ether-based resin composition. When the silicone oil is used in an amount of less than 0.1% by weight, sufficient impact reinforcement effect can not be obtained. When the silicone oil is used in an amount exceeding 10% by weight, mechanical properties may be lowered.
