    Abstract: A method for the preparation of polyisocyanurate foams with reduced thermal conductivity, comprises reacting optionally modified organic polyisocyanates (A) with at least one high mol.wt. compound (B) containing two or more reactive hydrogen atoms and optionally with low mol.wt. chain extenders and/or cross-linking agents (C), in the presence of catalysts (D), optional propellants (E) and optional auxiliary agents and/or additives (F). At least one recycled polyol obtained by glycolysis of polyisocyanurate foam using carrier polyols with a maximum OH content of 500 mg KOH/g and molar mass of at least 450 g/mole, is used as (B). Also claimed are polyisocyanurate foams prepared by the above method.

    Abstract: An agent for the surface modification of fillers for polyamide compositions comprises: (A) an amino-functional silane, a bis-aminosilane a tertiary aminosilane or an oligomer of these; (B) a mixture of an amino-functional silane, bis-aminosilane and/or tertiary aminosilane and an alkyl-, alkenyl- or polyether-functional silane and optionally an oligomer of these; or (C) a mixture of an alkyl-functional silane and an alkenyl-functional silane and optionally an oligomer of these. An agent for the surface modification of fillers for polyamide compositions comprises either: (A) an agent comprising: (i) an amino-functional silane of formula (Ia); (ii) a bis-aminosilane (Ib); (iii) a tertiary aminosilane (Ic); or an oligomer of (Ia)-(Ic) with a degree of oligomerization (DO) of 2-20; (B) a mixture of: (i) a component comprising (a) an amino-functional silane of formula (IIa), (b) a secondary aminosilane (IIb) and/or (c) a tertiary aminosilane (IIc); and (ii) a component comprising either (a) an alkyl-functional silane of formula (III), (b) an alkenyl-functional silane of formula (IV), (c) a polyether-functional silane of formula (V); and optionally (iii) an oligomer of (IIa)-(IIc) and (III)-(V) with a DO of 2-20; or (C) a mixture of: (i) an alkyl-functional silane of formula (IIIa); and (ii) an alkyl-functional silane of formula (IV); and optionally (iii) an oligomer of (IIIa) and (IV) with a DO of 2-20. RNH-(CH2)3-Si(Me)x(Z)3-x (Ia) Z = 1-3C alkoxy, OH or Cl; x = 0 or 1; and R = 1-20C alkyl, 5-12C cycloalkyl or 6-12C aryl. R-Si(Me)x(Z)3-x (IIa) Z = 1-3C alkoxy, OH or Cl; x = 0 or 1; R = H2N((CH2)2NH)y(CH2)3; and y = 0-2. R'-Si(Me)x(Z)3-x (IIIa) Z = 1-3C alkoxy, OH or Cl; x = 0-1; and R' = optionally fluorinated 1-16C alkyl or cycloalkyl. CH2=CH(CH2)n-Si(Me)x(Z)3-x (IV) Z = 1-3C alkoxy, OH or Cl; x = 0 or 1; and n = 0-20. R(OCH2CHR')nO(CH2)mSi (Me)x(Z)3-x (V) z = 1-3C alkoxy, OH or Cl; x = 0 or ; R = 1-4C alkyl; R' = H or Me; n = 5-20; and m = 2 or 3. Independent claims are also included for the following: (1) a filler surface-modified with the above agent; (2) an article comprising the surface-modified filler; (3) a filled polyamide composition produced using the surface-modified filler; and (4) an article based on the filled polyamide composition.

    Abstract: The prodn. of isocyanurate gp.-contg. polyols (I) comprises reacting polyisocyanurates (II) with short-chain, OH gp.-contg. cpds. (III) in presence of carrier polyols (IV) with an OH number of not more than 500 mg KOH/g and a mol. wt. of at least 450. Also claimed are polyols (I) obtd. by this process. Pref. polyols (IV) are based on glycerol and/or trimethylolpropane. The ratio of (III):(IV) = (5-20):1, and the ratio of (III + IV):(II) = (1-5):1. The process comprises heating the mixt. of (III) and (IV) to 190-240 degrees C, adding (II), reducing the temp. by 10-40 degrees C and stirring for 1.5-3 hrs. at this temp. After reaction is complete, the mixt. is either (a) cooled to 50-150 degrees C, treated with not more than 5 wt% alkali or alkaline earth metal hydroxide and stirred for 0.5-1.5 hrs. at this temp. or (b) cooled to 100-160 degrees C, treated with not more than 10 wt% monofunctional glycidyl ether and stirred for 0.5-1.5 hrs. at this temp.
