  • Patent number: 9617389
    Abstract: An stable ethylsilicate polymer having a dynamic viscosity of 10 centipoises (cps) to 1,000 cps at 25° C. and 50 wt % to 60 wt % silica (SiO2). The stable ethylsilicate polymer includes not greater than 1 wt % of TEOS monomer. The process of forming the ethylsilicate polymer includes a two step addition of catalysts. A hydrolysis catalyst is added initially, for example hydrochloric acid, and a second catalyst is added subsequently, such as phosphonitrilic chloride trimer. The ethylsilicate polymer is used to form MQ resins.
    Type: Grant

  • Patent number: 8829144
    Abstract: An MQ resin including at least 30% SiO2, preferably at least 50 wt % SiO2, and having dynamic viscosity of 50 centipoises (cps) to 750 cps at 25° C. is produced from a stable ethylsilicate polymer. The ethylsilicate polymer includes not greater than 1 wt % of TEOS monomer. The ethylsilicate polymer is produced by a two step addition of catalysts wherein a hydrolysis catalyst, for example, hydrochloric acid is added initially and a second catalyst, such as phosphonitrilic chloride trimer, is added subsequently.

  • Patent number: 5075351
    Abstract: There are provided reinforcing additives, e.g., for polyolefins, comprising (a) a hydrolyzable silane having an ethylenically unsaturated amide substituent and (b) a free radical generator. Also provided is a single step method of using such additives with hydroxyl-containing reinforcements, such as mica to improve processability and physical and thermal resistance properties of reinforced resin compositions.

  • Patent number: 4031044
    Abstract: A method is disclosed in which polyether based high resilient polyurethane foams are produced. The foams have low shrinkage and are free of voids. These two main physical properties are obtained without the sacrifice of other important physical properties. The results are achieved by utilizing novel siloxane-oxyalkylene copolymeric foam stabilizers.
