  The aim of the present invention is to provide a multi-branched polymer, in which branch terminals can be easily modified and which have a high degree of branching and narrow dispersion. By polymerizing a compound having 2 or more polymerization-initiation sites and polymerizable unsaturated bonds with a living radical polymerization method using a metal catalyst, it is possible to produce a multi-branched polymer with narrow dispersion and a high degree of branching and having repeating units represented by the formula (I): wherein R 1 to R 3 each independently represents hydrogen or a hydrocarbon group, R 1 may be bonded to R 3 to form a ring; X represents a connecting group having a valence of 3 or higher; Y may be the same or different and each represents a functional group which may have a halogen atom at a terminal thereof; and a is an integer of 2 or larger.

  本发明的目的是提供一种多支化聚合物，其中支链末端可以容易地修改，并具有高度分支和窄分散度。通过使用金属催化剂的活性自由基聚合方法聚合具有2个或更多聚合引发位点和可聚合不饱和键的化合物，可以产生具有窄分散度和高度分支的多支化聚合物，并具有由式（I）表示的重复单元：其中R1至R3各自独立表示氢或碳氢基团，R1可以与R3连接形成环；X表示具有3或更高价的连接基团；Y可以相同或不同，每个表示具有末端可能有卤素原子的功能基团；a是2或更大的整数。

  A surgical tissue adhesive composition contains at least one 1,1-disubstituted electron-deficient olefin macromer. The adhesive composition of the invention has improved biocompatibility as well as controlled biodegradation characteristics and bioactivity. Adhesive co-monomer compositions contain at least one macromer with a pendant oligomer, polymer, or peptide chain as an acrylic ester of the reactive olefin. The polymers formed therefrom have a grafted brush-like nature. The composition is particularly useful for creating an adhesive bond at the junction of living tissue in surgical applications. The adhesive composition may further comprise co-monomer, co-macromer, cross-linker, or inter-penetrating polymer compounds containing peptide sequences that are bioactive or enzyme responsive. The peptide sequences are selected to promote tissue infiltration and healing in a particular biological tissue. The sequences may contain specific cell-adhesion, cell-signaling, and enzyme-cleavable domains. Furthermore, a degradable filler material may be included in the composition to create a reinforced composite. The filler preferably has a higher degradation rate than the polymer matrix, generating porosity upon degradation. The adhesive may further contain entrapped or incorporated drugs or biologics, including antibiotics or growth factors. The adhesive can be used to bind together the edges of living tissues during surgical procedures. The cured composition provides interfacial bonding and mechanical fixation while promoting tissue infiltration and replacement of the adhesive polymer.

  A polymer comprising recurring units (2) obtained through polymerization of an ester compound of formula (1) is used to form a resist composition. R 1 is F or C 1 -C 6 fluoroalkyl, R 2 is H or C 1 -C 8 alkyl, R 3 is O or C 1 -C 6 alkylene, R 4 and R 5 each are H or C 1 -C 10 alkyl or fluoroalkyl, and R 6 is H or an acid labile group. The resist composition, when processed by ArF lithography, has advantages including improved resolution, transparency, minimal line edge roughness, and etch resistance. The resist composition exhibits better performance when processed by ArF immersion lithography with liquid interposed between a projection lens and a wafer.
