摘要： An aqueous sizing composition for glass fibers used to reinforce polyolefin polymers contains coupling agent, chemically modified polyolefin film forming material, and stabilizer. The stabilizer is one or more of the following: i) phosphinates selected from the group consisting of alkali metal phosphinates, alkaline earth metal phosphinates, ammonium phosphinate, organic phosphinates and mixtures thereof; ii) phosphonites selected from the group consisting of alkali metal phosphonites, alkaline earth metal phosphonites, ammonium phosphonite, organic phosphonites and mixtures thereof; iii) phosphites selected from the group consisting of alkali metal phosphites, alkaline earth metal phosphites, ammonium phosphite, organic phosphites and mixtures thereof; iv) hypophosphites selected from the group consisting of alkali metal hypophosphites, alkaline earth metal hypophosphites, ammonium hypophosphite and mixtures thereof; v) sulfites selected from the group consisting of alkali metal sulfites, alkaline earth metal sulfites, ammonium sulfite and mixtures thereof. vi) bisulfites selected from the group consisting of alkali metal bisulfites, alkaline earth metal bisulfites, ammonium bisulfite and mixtures thereof; and vii) mixture of one or more of the stabilizers of i through vi with an antioxidant selected from the group consisting of hindered phenols, diarylamines, thioethers and mixtures thereof, Optionally the size contains as a lubricant one or more partial esters of a branched carboxylic acid copolymer present. Sized glass fibers prepared with the aforesaid sizing composition result in improved color and mechanical properties in polyolefin composites reinforced with the sized fibers.
