Novolac resins and use in rubber compositions
A resorcinolic novolac resin composition comprising the reaction product of (i) an aldehyde or ketone, and (ii) aralkyl-substituted resorcinol and resorcinol, where the moles of the aralkyl-substituted resorcinol to the total moles of the resorcinol and aralkyl-substituted resorcinol is 0.01:1 to 0.4:1.
Polymeric surface having reduced biomolecule adhesion to thermoplastic articles of such substrate
A substrate is described having a treated contact surface comprising a carbon or silicon compound comprising from 1 to 30 atomic percent oxygen, from 0.1 to 30 atomic percent nitrogen, or both, each as measured by XPS. The treated contact surface has a biomolecule recovery percentage greater than the biomolecule recovery percentage of the surface before treatment according to the method.
Surface modification of cellulose nanocrystals
Hydrophobic CNCs were successfully prepared by grafting amine- and thiol terminated hydrocarbons to CNCs that have been previously coated with plant polyphenols. Hydrocarbons of various chain lengths can be used to tune the hydrophobicity of the modified CNCs. After the surface modification process, CNCs can be easily redispersed in nonpolar solvents highlighting the potential of the hydrophobic CNCs in, for example, CNC reinforced nanocomposites and non-aqueous formulations.
