Surface dynamics for poly(vinyl alkylate)s via dynamic contact angle and adhesion tension relaxation

Effect of alkyl side chain substitution on molecular structure of comb-like poly(2-hydroxyethyl methacrylate) derivatives

“…Intuitively, it might be expected that the ordering of comb-like copolymers would be increased as the degree of substitution was increased because long alkyl chains induce a well-aligned side chain structure in comb-like polymers. [10][11][12] However, in the present study, we observed unusual trends in molecular structure formation depending on the degree of substitution of long alkyl side chains in the comb-like copolymer system.…”

Terpolymers Composed of Ethyl Acrylate, Methoxypolyethyleneglycol Methacrylate and Methoxypolypropyleneglycol Methacrylate as Pressure Sensitive Adhesives and their Blood Compatibility

“…We measured DCA at a dipping velocity of 20 mm/min. The principle of the method has been described in detail elsewhere [ 3 ] .…”

“…The principle of this method was described elsewhere [3]. The measurement was performed as follows: first, the sample plate was mounted so that the bottom was just in contact with the liquid surface; then it was lowered 20 mm at a velocity of 100 mm/min and stopped.…”

Surface properties and liquid crystal alignment behavior of poly(2-hydroxyethyl methacrylate) derivatives with alkyl ester side chains

“…Comb-like polymers with functional side chains have been widely used to investigate the correlation between molecular structures and wettability [8][9][10][11][12]. The introduction of long alkyl groups in the side chain of such polymers has been regarded as a general method to obtain well ordered structures giving rise to the very low surface energy [13][14][15]. The type of backbone and linking group in the polymers can also significantly affect the molecular structures and wettability [6,[14][15][16][17][18].…”

In this paper, the influence of ester and alkyl groups on the molecular structure and wettability of the polymers were studied through varying # in the alkyl side groups.
