A temperature-responsive substrate having on its surface a layer containing at least one polymer, the at least one polymer being responsive to temperature and containing a fluorine-containing monomer-derived unit. Also disclosed is a polymer and composition for use in producing the substrate, as well as methods for producing, using and evaluating the substrate.

Temperature-responsive base material, method for producing same, and method for evaluating same

The present invention aims to provide a heat-curable composition that is capable of providing a cured product having low vapor permeability, a low linear expansion coefficient, and a low refractive index. The present invention relates to a curable composition including a fluorine-containing polymer having a hydroxyl value of 100 mgKOH/g or higher and a refractive index of 1.42 or lower and an epoxy compound.

Curable composition

Provided is an aqueous emulsion composition which has excellent chemical stability (stability with respect to impurities) and excellent mechanical stability. Disclosed is an aqueous emulsion composition which contains: (A) a polymer that contains a fluoroalkyl group; and (B) a surfactant that contains (B1) an amidoamine surfactant having an amide group and an amino group, and (B2) a nonionic surfactant. It is preferable that the surfactant does not contain a monool having an unsaturated triple bond or an alkylene oxide addition product of a polyol.

Aqueous emulsion composition

Disclosed is a fluorine-containing polymer prepared by polymerizing (I) a polyfluoroalkyl group-containing (meth)acrylate which is substituted at alpha-position, in the presence of (II) a blocked isocyanate compound. A water- and oil-repellent composition containing the fluorine-containing polymer can impart the excellent water- and oil-repellency, and excellent durability thereof to substrates.

Fluoropolymers and treatment agent

Disclosed is a method for producing a fluorine-containing copolymer composition wherein a fluorine-containing copolymer is produced by polymerizing 1-99 weight % of a monomer mixture (A) containing a polymerizable monomer having a fluoroalkyl group and a polymerizable monomer having a hydrophilic group in the presence of 1-99 weight % of a surfactant (B) containing a surfactant having an oxyalkylene group. The total amount of the monomer mixture (A) and the surfactant (B) is not less than 80 weight % of the polymerization system.

Method for producing fluorine-containing copolymer and soil release agent containing same

An aqueous dispersion type fluorine-containing water- and oil-repellent composition containing a polymer of a perfluoroalkyl group-containing ethylenically unsaturated monomer dispersed in an aqueous medium. The composition also contains a nonionic surfactant having an HLB value of at most 11 and a cationic surfactant. A homopolymer of at least one monomer constituting the polymer has Tg of at most 50&#xb0; C.

Aqueous dispersion type fluorine-containing water- and-oil repellent composition having a polymer of a perfluoroalkyl group- containing etheylenically unsaturated monomer, a nonionic surfactant ana cationic surfactant, and preparation and use thereof

A flow control device constructed at a switch device for connecting a plurality of ring networks for exchanging data of a cell among the ring networks. A user device for transmitting a cell carrying data is connected to each ring network, and it can transmit cells within a window counter number. Such flow control device comprises a buffer monitoring unit for monitoring the number of data in an output buffer, a regulation judging unit for comparing the number of data in each buffer with a first threshold value representing state of the buffer which is in danger of overflow, with a second threshold value representing state of the buffer which is not in danger of overflow, and outputting a regulation notice when the data number is grater than the first threshold value while outputting a regulation notice when the data number is smaller than the second threshold value, and a plurality of traffic controlling units for transmitting to the respective ring network a reset cell at a first interval when no regulation notice is received or the release notice is received while transmitting a reset cell at a second interval which is longer than the first interval when the regulation notice is received.

Flow control method

Disclosed is a data transmission unit for use in a system wherein data to be transmitted is organized into packets which may be assigned one of four states: idle, occupied, released, or reset. Or these packets may be assigned one of three states: idle, occupied, or released, each state being able to include a reset bit. Each unit has terminals associated therewith and is assigned two windows on the number of packets it may transmit. One window is a parameter for transmitting data by using idle packets and the other is by using released packets. The unit responds to the state of a received packet, the state of the windows, and the presence or absence of transmit data to control whether the packet transmitted out of the unit is a packet from internal transforming buffers, a released packet from a released cell producing circuit, an occupied packet containing data from the unit's own terminals. A released packet contains the address of the unit which generated it and is generated when there is no data to be transmitted and an idle packet is received by the unit. Any unit can occupy a released packet with data from its terminal within the second window band, thereby increasing data throughput.

Data transmission system with packets having occupied, idle, released,

A packet communications network for transmitting data between nodes by the use of cell slots circulating the network includes a center node inserted in the ring network for sequentially generating, at a selected rate, first and second types of cell slots interleavingly for transmitting first and second types of data, respectively. Each cell slot has a type code for identifying either one of the first and second types, and a status code for identifying the different status of the cells. Each node detects whether the received cell is the first type or the second type. If the received cell is the first type, it is used for transmitting the connection-oriented data under MARS system. If the received cell is the second type, it is used for transmitting the connectionless data under ATMR system.
