#CMT# #/CMT# Preparing crosslinked organic polymer comprises reacting a polymer with a crosslinking agent comprising 1,3,5-trialkyl triazine trione derivative (I) or 2,4,6-trisalkoxy triazine derivative (II). #CMT# : #/CMT# Preparing crosslinked organic polymer comprises reacting a polymer with a crosslinking agent comprising 1,3,5-trialkyl-triazine trione derivative of formula (I) or 2,4,6-trisalkoxy triazine derivative of formula (II). R 1>-R 3> : divalent spacer carbon group comprising 1-20C alkylene, preferably 1-6C alkylene, 2-20C alkenylene, preferably 2-8C alkenylene (all optionally branched), 6-14C aromatic hydrocarbon (mono- or bicyclic and optionally substituted by 1-4 alkyl or 1-3C alkenyl), 6-14C bivalent cycloaliphatic (all optionally comprise N, S or O), 5-12C cycloalkyl, 5-12C cycloalkenyl or 5-12C cycloalkyldienyl (mono- or bicyclic and optionally substituted by 1-3 alkyl or 1-3C alkenyl). Independent claims are also included for: (1) (I) and (II) excluding trialkylphenyl cyanurate, tris(2-methyl-2-propenyl)cyanurate and tributenylisocyanurate; and (2) a crosslinkable composition comprising a polymer consisting of polyvinyl polymers, polyolefins, polystyrenes, polyacrylates, polymethacrylates, polyesters, polyamides, polycarbonates, polyphenylene ethers, polyphenylene sulfides, polyacetals, polyphenylene sulfones and/or fluoropolymers and (I) or (II). #CMT#[Image]#/CMT# #CMT#USE : #/CMT# The crosslinked organic polymer is useful in the field of electronics, preferably in connectors, contact holders and printed circuit boards. #CMT#ADVANTAGE : #/CMT# The crosslinking agent used in the method exhibits high thermal stability and increased crosslinking capacity. The crosslinked organic polymer exhibits high thermo-mechanical stability and high heat resistance. #CMT#POLYMERS : #/CMT# Preferred Components: The polymers comprise thermoplastic polymers comprising polyvinyl polymers, polyolefins, polystyrenes, polyacrylates, polymethacrylates, polyesters, polyamides, polycarbonates, polyphenylene ethers, polyphenylene sulfides, polyacetals, polyphenylene sulfones and/or fluoropolymers. The amount of (I) or (II) used in the method is 0.01-10 wt.%, based on the crosslinkable polymer. Preferred Method: The crosslinking is carried out on the basis of the polymer to be crosslinked either with the addition of a suitable peroxide at 160-90[deg] C or by electron beam crosslinking at room temperature. #CMT#DEFINITIONS : #/CMT# Preferred Definitions: R 1>-R 3> : phenylene or cyclohexanyl. #CMT#EXAMPLE : #/CMT# No suitable example given. |
