| 摘要 |
The invention relates to glass strands coated with an essentially aqueous sizing composition which comprises the combination of at least one bissilane (A) of formula in which: R1, R2, R3, R4, R5 and R6, which are identical or different, represent a C1-C6, preferably C1-C3, alkyl radical, Z represents a C1-C16 hydrocarbonaceous chain which can comprise one or more N, O and/or S heteroatoms, and of at least one unsaturated monosilane (B) chosen from vinylsilanes and (meth)acrylosilanes. The glass strands obtained exhibit an improved ability to be cut which renders them capable of being used to reinforce polymers, in particular by moulding by simultaneous spraying. |
