| 摘要 |
The invention concerns glass yarns coated with an essentially aqueous sizing composition, which comprises the combination of: at least a bis-silane (A) of formula (I), wherein: R1, R2, R3, R4, R5 and R6, identical or different, represent a C1-C6 alkyl radical, preferably C1-C3; Z represents a C1-C16, hydrocarbon chain capable of containing one or several N, O and/or S heteroatoms; and at least an unsaturated monosilane (B) selected among vinylsilanes and (meth)acylosilanes. The resulting glass yarns have improved cuttability which makes them appropriate for reinforcing polymers, in particular by simultaneous spray moulding. |
