Paper sizing agent comprised of reaction product of maleic anhydride and propylene oligomers |
摘要 |
A paper sizing agent is disclosed. The sizing agent is obtained by alkali saponification of a reaction product which is obtained by reacting a propylene oligomer with maleic anhydride under heating in the absence of a catalyst. The propylene oligomer contains substantially no oligomers having 10 or less carbon atoms. Further, the content of oligomers having 11 to 12 carbon atoms is 0 to 30% by volume, the content of oligomers having 13 to 15 carbon atoms is 20 to 95% by volume and the content of oligomers having 16 to 21 carbon atoms is 5 to 50% by volume. The paper sizing agent provides a homogeneous transparent sizing agent, which restrains the amount of the foaming and also has improved sizing effects.
