摘要:
SENSITIVITY IN ANAEROBIC SEALANTS AND ADHESIVES TO THE SURFACES TO WHICH THEY ARE APPLIED IS MATERIALLY REDUCED BY USING AS AN INITIATOR FOR POLYMERIZATION A COMBINATION OF A HYDROPEROXIDE AND AN ORGANIC PEROXIDE.
摘要:
wherein Rf represents an unbranched or branched perfluoroalkyl radical with 3 to 12 carbon atoms, R represents hydrogen or fluorine, and R1 and R2 represent hydrogen or methyl and m is 1 or 2, n is a whole number from 2 to 12, and p is a whole number from 1 to 3, and optionally of other copolymerisable, ethylenically unsaturated monomeric compounds are provided. The polymerisation products can be homopolymers or copolymers. The polymerisation products are useful for producing oleophobic, hydrophobic or dirt repellent finishes on various substrates.

A method of applying and curing a polyester-acrylate containing coating composition with minimum volatility and toxic odor comprises adding to the composition N-vinyl pyrrolidone and applying the composition at low viscosity to a substrate and subjecting the coating to actinic light to cure.
摘要:
A light sensitive polymer, susceptible to crosslinking on exposure to actinic light. The polymer contains the recurring unit: R1, R2 and R3 are each selected from the group consisting of hydrogen, halogen and lower alkyl. At least one of R4 and R5 is an azidobenzoyloxy or azidonaphthoyloxy group. The other of R4 and R5 is selected from the group consisting of hydroxyl, halogen, alkoxy, aryloxy, aralkoxy, alkoxyalkoxy, aryloxyalkoxy, alkoxyaryloxy, aryloxyaryloxy, alkylacyloxy, arylacyloxy, alkenylacyloxy, aralkenylacyloxy, heterocyclic substituted alkenylacyloxy, azidobenzoyloxy and azidonaphthoyloxy.
